When bonding is performed using the photocurable resin, the photocurable resin is attached to one of the liquid crystal panel and the bonding member. After these are applied and brought into close contact, the liquid crystal panel and the bonding member are bonded together by irradiating with ultraviolet rays.

Hereinafter, embodiments of an electro-optical device manufacturing method, an electro-optical device, and an electronic apparatus to which the present invention is applied will be described with reference to the drawings.
(First embodiment)
First, prior to the description of the method for manufacturing the electro-optical device according to the present embodiment, the configuration of the electro-optical device obtained thereby will be described.
(Constitution)
FIG. 1 is a diagram showing an overall configuration of an electro-optical device 100 according to the first embodiment of the present invention.
In the following description, in order to show the characteristic part of the structure in an easy-to-understand manner, the structure in the drawing may be shown with its dimensions and scale different from those of the actual structure.

FIG. 1A is a perspective exploded view schematically showing a schematic configuration of the electro-optical device of this example, and FIG. 1B is a cross-sectional view taken along the line BB ′ in FIG. is there.
As shown in FIG. 1A, the electro-optical device 100 includes an electro-optical panel 110 and a translucent member 120 bonded to one side of the electro-optical panel 110 via an adhesive layer 130. Yes. In this example, the electro-optical panel 110 and the translucent member 120 are both substantially rectangular in plan view. Hereinafter, in the XYZ orthogonal coordinate system shown in FIG. The long side direction of 110 and the Y direction are the short side direction of the electro-optical panel 110, and the Z direction is the thickness direction of the electro-optical panel 110.

  The electro-optical panel 110 includes an electro-optical material layer and a means for applying a voltage to the electro-optical material layer. It is possible to take out desired light by changing the state of the electro-optic material layer by applying a voltage based on an electric signal. Specific examples of the electro-optical panel include a liquid crystal panel using a liquid crystal material for an electro-optical material layer, an organic EL panel using an organic electroluminescent material, an electrophoretic panel using an electrophoretic material, and a plasma-like material. A plasma panel etc. are mentioned. In this example, a liquid crystal panel is employed as the electro-optical panel.

  The liquid crystal panel (electro-optical panel) 110 of this example includes an active matrix type array substrate 111, a color filter substrate 112 disposed opposite thereto, and a liquid crystal layer (electro-optical material layer) sandwiched between the substrates. 114. A sealing material 115 is provided on the periphery of the color filter substrate 112, and the liquid crystal layer 114 is sealed between the array substrate 111 and the color filter substrate 112 by the sealing material 115. The portion that overlaps with the sealant 115 is a region that is a frame-like frame portion when completed, and the region that overlaps with the sealant 115 on the lower surface of the color filter substrate 112 (the surface facing the array substrate 111) has a light-shielding property. A black mask 112a is formed. Further, an alignment mark 113 is provided on the positive side in the Z direction in the portion overlapping with the black mask 112a.

  Although the detailed structures of the array substrate 111 and the color filter substrate 112 are not shown, the array substrate 111 is provided with a large number of scanning lines extending in the X direction and a large number of data lines extending in the Y direction. The scanning line is electrically connected to a scanning line driving circuit that supplies an investigation signal, and the data line is electrically connected to a data line driving circuit that supplies an image signal. The data lines and the scanning lines are orthogonal to each other, and a thin film transistor (TFT) that switches an image signal based on an investigation signal is provided in the vicinity of the intersection.

  One area divided into the data line and the scanning line is a sub pixel, and one sub pixel corresponding to each of R (red), G (green), and B (blue) is set as one pixel. It is composed. Each of the subpixels is provided with a pixel electrode electrically connected to the TFT, a common electrode, and the like. When an image signal is transmitted to the pixel electrode, an electric field is generated between the pixel electrode and the common electrode, and the azimuth angle of the liquid crystal molecules in the liquid crystal layer 114 is controlled by this electric field. As a method for controlling the azimuth angle of liquid crystal molecules, any of a vertical electric field method such as a TN method and a VA method and a horizontal electric field method such as an FFS method and an IPS method may be used. In general, in the vertical electric field type, the pixel electrode is provided on the array substrate, and the common electrode is provided on the color filter substrate. In the horizontal electric field type, both the pixel electrode and the common electrode are provided on the array substrate.

  The color filter substrate 112 is provided with a color material portion corresponding to each of the sub-pixels. Three types of color material portions corresponding to each of R (red), G (green), and B (blue) are periodically provided. For example, the color material portion corresponding to R absorbs wavelength band light other than red light, and the light passing therethrough is emitted as red light. Light emitted from the three sub-pixels becomes red light, green light, and blue light, respectively, and these are mixed and visually recognized to indicate the minimum unit of full color display.

  The adhesive layer 130 is made of a photo-curing adhesive that is cured by absorbing light energy and developing as a result of polymerization. The adhesive layer 130 of this example is formed by irradiating an adhesive containing an ultraviolet (UV) curable epoxy resin with ultraviolet rays, and an active region (a pixel effective for display is displayed on the bonding surface). It is arranged only in the formed region). Such an adhesive undergoes polymerization in accordance with the amount of light energy absorbed, and changes in composition and volume as the polymerization proceeds. The degree of polymerization (curing degree) can be controlled by controlling the amount of light energy to be irradiated. Specifically, the degree of curing increases as the light intensity of the irradiated light increases or as the irradiation time increases. Become. The adhesive has fluidity when the degree of cure is low, and the fluidity decreases and becomes difficult to deform as the degree of cure increases.

  The translucent member 120 is made of a translucent material such as glass, quartz, or plastic. The translucent member 120 transmits light emitted from the liquid crystal panel 110 and emits it to the Z positive direction side (viewing side), and has a function corresponding to the application of the electro-optical device 100. In this example, the cover glass 120 is employed as the translucent member, and the size thereof is approximately the same as that of the color filter substrate 112. In addition, a black mask 120 a is formed on the periphery of the upper surface (viewing side surface) of the cover glass 120 so as to overlap the black mask 112 a of the color filter substrate 112. The black mask 120a has a frame width larger than that of the black mask 112a of the color filter substrate 112 and a narrow opening at the center, and constitutes the appearance of the frame portion (the frame of the display screen viewed from the viewing side). Yes. Further, an alignment mark 121 is provided on the Z positive direction side in a portion overlapping with the black mask 120a. The alignment marks 113 and 121 are used for alignment of the liquid crystal panel 110 and the cover glass 120 when the electro-optical device 100 is manufactured.

In the present embodiment, the cover glass 120 has a function of protecting the viewing side of the liquid crystal panel 110, but may have other functions such as a function of limiting the viewing angle as necessary. is there.
In such an electro-optical device 100, when ultraviolet rays are irradiated to cure the ultraviolet curable adhesive, a region that is shielded by the black masks 112a, 120a and the like and is not irradiated with ultraviolet rays occurs.
For this reason, in the electro-optical device 100 according to the present embodiment, in the curing process using ultraviolet rays, the ultraviolet curable adhesive is not disposed in a region that is shielded by the black masks 112a and 120a and is not irradiated with ultraviolet rays from the direction of the light source. It is supposed to be.
Specifically, an ultraviolet curable adhesive is disposed only in an active region where pixels effective for display are formed without being covered by the black masks 112a and 120a.

Thereby, in the curing process by ultraviolet rays, ultraviolet rays are not irradiated to the ultraviolet curable adhesive, and it can be prevented from becoming an uncured state, and the adhesive is disposed on the entire active region, Display quality can be improved by suppressing display unevenness.
In addition, when the UV curable adhesive is in an uncured state, the uncured adhesive may leak from between the bonding surfaces of each member when assembling or using the product, resulting in a decrease in display function, etc. May occur.

(Method of manufacturing electro-optical device 100)
Next, an embodiment of a method for manufacturing an electro-optical device according to the present invention will be described based on the configuration of the electro-optical device 100 described above with reference to FIGS.
FIG. 2 is a flowchart showing a method for manufacturing the electro-optical device 100 according to the present embodiment.
FIG. 3 is a schematic diagram showing an execution example of the adhesive drawing process (step S5 in FIG. 2).
As shown in FIG. 2, in this embodiment, while forming the liquid crystal panel 110 by step S1-S3, a glass substrate is prepared as a base material of the liquid crystal panel 110, a glass substrate is divided into a some area | region, Is one array substrate formation region. Then, various wirings, elements, and the like are formed in each array substrate formation region collectively in a plurality of array substrate formation regions. In addition, a glass substrate is prepared as a base material of the color filter substrate 112, and a color material portion, a black matrix, and the like are formed in each of a plurality of color filter substrate formation regions as in the array substrate side.

Next, the glass substrate to be the array substrate 111 and the glass substrate to be the color filter substrate 112 are bonded together in a vacuum atmosphere via a spacer or the like (step S1).
Next, in the bonded state, one glass substrate is singulated for each array substrate forming region to form the array substrate 111, and the other glass substrate is singulated for each color filter substrate forming region. 112 is formed (step S2).
Thereby, the liquid crystal panel 110 is obtained by forming the liquid crystal layer 114 between the array substrate 111 and the color filter substrate 112 and sealing the same with the sealing material 115 (step S3).

  In addition, a glass substrate is prepared as a base material of the cover glass, and a function of limiting the viewing angle is provided by forming a slit or the like as necessary. Then, after the glass substrate is separated into a cover glass 120, it is cleaned. Thereby, the foreign substance removal of the surface of the cover glass 120 can be performed, and the side which adhere | attaches with the liquid crystal panel 110 can be cleaned, and it becomes possible to express the adhesiveness of an adhesive agent favorable (step S4).

Next, as shown in FIG. 3, by drawing (applying) an adhesive on the cover glass 120 using the dispenser 200, an adhesive drawing process (application process) is performed (step S5).
Specifically, first, the cover glass 120 is detachably fixed to the surface plate 210, and the relative position between the syringe 220 and the cover glass 120 is adjusted using, for example, the alignment mark 121 (see FIG. 1A). . Further, an adhesive containing an epoxy resin having ultraviolet curing properties is stored inside the syringe 220. Then, the adhesive is discharged from the syringe 220 while changing the relative position between the cover glass 120 and the syringe 220, and the adhesive is drawn on the cover glass 120.

Here, an adhesive is applied along the long side direction (X direction) of the cover glass 120, and the adhesive is disposed on the entire surface of the active region.
At this time, in a subsequent process, the liquid crystal panel 110 and the cover glass 120 are in close contact, and the adhesive is disposed so that the adhesive is disposed on the entire active region in a state where the adhesive is spread between the bonding surfaces. Apply the adhesive by subtracting the spread of the agent.
Note that, as described above, in the present embodiment, in order to set the application region so that the adhesive is not disposed in the portion that is not irradiated with ultraviolet rays, only in the opening (that is, the active region) in the black mask 120a of the cover glass 120. Adhesive is applied.

However, this is because it is assumed that ultraviolet rays are irradiated from the upper surface of the cover glass 120. When the ultraviolet rays are irradiated from the lower surface of the liquid crystal panel 110, the regions where the ultraviolet rays are shielded are different. In this case, as viewed from the lower surface of the liquid crystal panel 110, it is allowed to place an adhesive in a region irradiated with ultraviolet rays.
Therefore, the area where the adhesive is applied is applied such that (1) the adhesive is disposed at least over the entire active area in a state where the liquid crystal panel 110 and the cover glass 120 are in close contact with each other. In the curing step after the coating, the region satisfying the two determination criteria that the adhesive is applied only to the region that can be irradiated with ultraviolet rays from the upper surface of the cover glass 120 is set.

Next, in a vacuum atmosphere, the liquid crystal panel 110 and the cover glass 120 on which the adhesive part 130a is disposed are pressed together in a state of alignment (step S6). As a result, the adhesive is spread between the liquid crystal panel 110 and the cover glass 120 to form the adhesive layer 130, and the liquid crystal panel 110 and the cover glass 120 are brought into close contact with each other due to the adhesiveness.
At this time, since the adhesive is applied by subtracting the spread amount of the adhesive as described above, the adhesive spread between the bonding surfaces is arranged only in the active region.

However, depending on the uneven application of the adhesive and the pressed state between the liquid crystal panel 110 and the cover glass 120, the adhesive may ooze out to a region where the ultraviolet ray is not irradiated in the curing process.
In order to properly cure such an adhesive, in this embodiment, in the following main curing step, ultraviolet rays are emitted from the upper surface of the cover glass 120, and a concave mirror is provided on the side of the liquid crystal panel 110 and the cover glass 120 that are in close contact with each other. It is installed, and the ultraviolet light irradiated from the upper surface is reflected by the concave mirror and irradiated from the side surface.
At this time, the focal point of the concave mirror is set at a position between the bonding surfaces from which the adhesive exudes.
This makes it possible to cure the adhesive that has oozed out of the active region more effectively in the curing process using ultraviolet rays.

Subsequently, after performing the 1st alignment process (arrangement process) of Step S7, the temporary adhesion process of Steps S8-S10 is performed.
That is, in step S7, alignment is performed using the alignment marks 113 and 121, and in step S8, ultraviolet rays are irradiated from the upper surface side of the cover glass 120 to perform the first temporary curing process.
In step S9, alignment is performed using the alignment marks 113 and 121 as in step S7. Thereby, even when the adhesive layer 130 has produced the distortion by the 1st temporary hardening process in step S8, position shift can be eliminated.

Next, in step S10, as in step S8, the second temporary curing process is performed by irradiating with ultraviolet rays. In the second temporary curing treatment, the energy imparted to the adhesive that is an epoxy resin is set to an amount equal to or greater than the amount required for the completion of polymerization minus the amount imparted by the first temporary curing treatment. In the present embodiment, the energy applied in the first temporary curing process is less than the energy applied in the second temporary curing process, for example, 30% in the first temporary curing process with respect to the amount necessary for the completion of polymerization, 70% or more is given by the second temporary curing treatment.
Thus, after the second temporary curing process, the adhesive layer 130 is almost completely polymerized, and the liquid crystal panel 110 and the cover glass 120 are temporarily bonded.
In the temporary curing process of steps S8 and S10, a part of the adhesive layer 130 is irradiated with ultraviolet rays from the upper surface side of the cover glass 120, and the liquid crystal panel 110 and the cover glass 120 are temporarily bonded. And

Next, in step S <b> 11, a main curing process (bonding process) is performed on the temporarily bonded liquid crystal panel 110 and cover glass 120. In the main curing process, the entire surface of the adhesive layer 130 is irradiated with ultraviolet rays from the upper surface side of the cover glass 120. At this time, the energy applied to the adhesive which is an epoxy resin is set to be equal to or higher than the energy required for the completion of polymerization.
In the main curing process of step S11, the entire adhesive layer 130 is irradiated with ultraviolet rays from the upper surface side of the cover glass 120, and a concave mirror is installed on the side of the temporarily bonded liquid crystal panel 110 and cover glass 120. , Irradiate ultraviolet rays to the side by reflecting ultraviolet rays. At this time, as described above, the focal point of the concave mirror is set to the position of the adhesive that has oozed out of the active region.
In step S11, when the adhesive contains a thermosetting component, the thermosetting treatment is also performed, the adhesive is sufficiently cured, and the liquid crystal panel 110, the cover glass 120, Adhere this.

(Configuration of UV curing device)
Next, the configuration of the UV curing apparatus that performs the temporary curing process in steps S8 and S11 and the main curing process in step S11 will be described.
FIG. 4 is a diagram illustrating a configuration example of the UV curing apparatus 300 according to the present embodiment.
In FIG. 4, a UV curing apparatus 300 includes a table 301, a table moving mechanism 302, a positioning mechanism 303, an imaging unit 304, a control unit 305, a temporary curing irradiation mechanism 306, and a main curing irradiation mechanism 307. And a concave mirror 308 and an ultraviolet ray generator 309.

  The table 301 is a pedestal on which the cover glass 120 and the liquid crystal panel 110 that are in close contact with an uncured adhesive are placed, and the placed liquid crystal panel 110 and the cover glass 120 are detachably fixed by vacuum suction. . In the present embodiment, the liquid crystal panel 110 and the cover glass 120 that are in close contact with each other are placed on the table 301 so that the liquid crystal panel 110 is a lower layer.

The table moving mechanism 302 is a moving mechanism that moves the table 301 in the irradiation chamber R for irradiating ultraviolet rays. Based on an instruction signal from the control unit 305, the table moving mechanism 302 is below the temporary curing irradiation mechanism 306 or the main curing irradiation. The table 301 is moved to a position such as below the mechanism 307. The table moving mechanism 302 includes a lifting mechanism that changes the height position of the table 301, and adjusts the height of the table 301 based on an instruction signal from the control unit 305.
The positioning mechanism 303 has a function of detachably adsorbing a curing object such as the cover glass 120 by vacuum adsorption, and based on an instruction signal from the control unit 305, the position (height position) of the adsorbed curing object. , Front / rear / left / right position, in-plane rotation position, etc.).

The imaging unit 304 photographs the liquid crystal panel 110 and the cover glass 120 placed on the table 301 and detects their relative positions with reference to the alignment marks 113 and 121. Then, the imaging unit 304 outputs data indicating the detected relative position between the liquid crystal panel 110 and the cover glass 120 to the control unit 305.
The control unit 305 controls the entire UV curing apparatus 300. In the temporary curing process and the main curing process using ultraviolet rays, the table moving mechanism 302, the positioning mechanism 303, the temporary curing irradiation mechanism 306, the main curing process, and the like of the UV curing apparatus 300 are performed. The curing irradiation mechanism 307 and the ultraviolet ray generator 309 are controlled.

  Specifically, when performing the temporary curing process, the control unit 305 controls the table moving mechanism 302 to move the table 301 below the temporary curing irradiation mechanism 306. Based on the data input from the imaging unit 304, the table moving mechanism 302 and the positioning mechanism 303 are controlled to adjust the relative positions of the liquid crystal panel 110 and the cover glass 120. Further, the control unit 305 controls the ultraviolet ray generator 309 to irradiate the liquid crystal panel 110 and the cover glass 120 with ultraviolet rays from the temporary curing irradiation mechanism 306. At this time, as will be described later, the provisional curing irradiation mechanism 306 converges the ultraviolet rays by the lens, and irradiates the ultraviolet rays to a part of the adhesive layer 130 disposed on the liquid crystal panel 110 and the cover glass 120.

Further, when performing the main curing process, the control unit 305 controls the table moving mechanism 302 to move the table 301 below the main curing irradiation mechanism 307. The control unit 305 controls the ultraviolet ray generator 309 to irradiate the liquid crystal panel 110 and the cover glass 120 with ultraviolet rays from the main curing irradiation mechanism 307. At this time, as will be described later, the main curing irradiation mechanism 307 irradiates the entire region of the adhesive layer 130 disposed on the liquid crystal panel 110 and the cover glass 120 with ultraviolet rays.
The pre-curing irradiation mechanism 306 has a lens that guides the ultraviolet rays generated by the ultraviolet ray generator 309 to the inside by an optical fiber and converges the guided ultraviolet rays. Then, the temporary curing irradiation mechanism 306 irradiates the ultraviolet rays with focusing on the position of the adhesive layer 130 where temporary curing is performed.

  The main curing irradiation mechanism 307 guides the ultraviolet rays generated by the ultraviolet ray generator 309 to the inside through an optical fiber, and irradiates the entire region of the adhesive layer 130 with the guided ultraviolet rays. The main curing irradiation mechanism 307 includes a concave mirror 308 that irradiates the liquid crystal panel 110 and the cover glass 120 disposed for performing the main curing with ultraviolet rays from the side. The concave mirror 308 is installed on the side of the central portion of each side of the substantially rectangular liquid crystal panel 110 and the cover glass 120, and the orientation is adjusted so that the focal point is located between the liquid crystal panel 110 and the cover glass 120. Has been. The concave mirror 308 reflects the ultraviolet light irradiated from above the cover glass 120 by the main curing irradiation mechanism 307 and irradiates the adhesive layer 130 from the side of the cover glass 120 and the liquid crystal panel 110.

The ultraviolet ray generator 309 includes an ultraviolet light source such as an ultraviolet lamp, and outputs ultraviolet rays to the temporary curing irradiation mechanism 306 or the main curing irradiation mechanism 307 based on an instruction signal from the control unit 305.
With the UV curing device 300 having such a configuration, the steps S7 to S11 are executed, and the adhesive layer 130 is cured while aligning the liquid crystal panel 110 and the cover glass 120. The cover glass 120 is bonded.
As described above, in the method of manufacturing the electro-optical device according to the present embodiment, the coating process is performed so that the adhesive layer 130 is disposed only in the active region irradiated with ultraviolet rays from above the cover glass 120 in the curing process. Apply the adhesive at.

Therefore, when ultraviolet rays are irradiated from above the cover glass 120 in the curing step, it is possible to prevent the ultraviolet rays from being blocked by the black mask 120a and the like and to generate an adhesive that is in an uncured state.
Therefore, the liquid crystal panel 110 and the cover glass 120 can be bonded together more appropriately using an adhesive of UV curable resin.
In addition, since the adhesive is disposed on the entire surface of the active area, display quality can be improved by suppressing display unevenness.
In the method of manufacturing the electro-optical device according to the present embodiment, a concave mirror is installed on the side of the liquid crystal panel 110 and the cover glass 120 that are in close contact with each other, and in the main curing process, ultraviolet rays are irradiated from above the cover glass 120. The ultraviolet rays irradiated from above are reflected by the concave mirror, and the ultraviolet rays are irradiated also from the side of the liquid crystal panel 110 and the cover glass 120.

Therefore, the adhesive that oozes out from the active region can be cured more reliably, and the adhesive can be prevented from being uncured.
Therefore, the liquid crystal panel 110 and the cover glass 120 can be more appropriately bonded using the adhesive of the UV curable resin.
In addition, as the UV curable adhesive used in the above-described embodiment, any of those having a property of being cured only by ultraviolet rays and those having a property of being cured by applying heat after the addition of ultraviolet rays can be used. is there.
In addition, when applying the adhesive in the present embodiment, it is also possible to place the adhesive only in the active region by screen printing.

(Second Embodiment)
Next, a second embodiment of the present invention will be described.
In the first embodiment, in the adhesive application step, the adhesive amount is applied to substantially the entire active area by subtracting the amount of spread when the liquid crystal panel 110 and the cover glass 120 are brought into close contact with each other.
On the other hand, in the present embodiment, an adhesive frame is formed on the peripheral edge of the active region and cured so that the adhesive layer 130 is disposed only in the active region more reliably, and the adhesive stains. An adhesive is applied in the active area in a state where the ejection is prevented.

In such a production method, a UV curable resin (hereinafter referred to as “adhesive”) having a property of developing tackiness when cured by ultraviolet rays can be used as an adhesive. When an adhesive is used, the members can be bonded together after curing, and the once bonded members can be peeled off.
Note that the configuration of the electro-optical device obtained by the manufacturing method according to the present embodiment is almost the same as the configuration of the electro-optical device 100 shown in FIG. 1, and therefore the configuration of the electro-optical device is described in the description of the first embodiment. I decided to.
FIG. 5 is a flowchart illustrating a method for manufacturing the electro-optical device 100 according to the present embodiment.

In FIG. 5, the steps S101 to S103 for manufacturing the liquid crystal panel 110 are the same as the steps S1 to S3 in FIG. 2 of the first embodiment.
Apart from the steps S101 to S103, a glass substrate is prepared as a base material for the cover glass, and a function of limiting the viewing angle is provided by forming a slit or the like as necessary. And after separating a glass substrate into the cover glass 120, this is wash | cleaned (step S104).

Next, the adhesive is drawn (applied) along the peripheral edge of the region that becomes the active region of the cover glass 120 (first application step), and the applied adhesive is irradiated with ultraviolet rays (first adhesion step). Thus, the first adhesive application / curing process is executed (step S105).
Specifically, using the dispenser 200 having an irradiation head capable of irradiating ultraviolet rays toward the tip of the nozzle that discharges the adhesive, the adhesive is applied along the peripheral edge of the region that becomes the active region, and the application is performed. The cured adhesive is cured by irradiating it with ultraviolet rays. As a result, the applied adhesive is quickly cured, and a frame portion can be formed along the peripheral edge of the region that becomes the active region.

At this time, the position where the adhesive is applied can be any position on the boundary line inside and outside the area that becomes the active area, inside the area that becomes the active area, or outside the area that becomes the active area.
However, in order to reliably hide the boundary between the frame portion in the active region and the internal region to which the adhesive is applied later from the viewer side, the frame portion is formed so as to surround the active region outside the region that becomes the active region. Is desirable.
In step S105, as described above, in addition to the case of using the dispenser 200 having the irradiation head capable of irradiating ultraviolet rays toward the tip of the nozzle that discharges the adhesive, a normal dispenser having no irradiation head is used. It is also possible to apply an adhesive using 200 and cure the adhesive with a UV curing device.

Next, the second pressure-sensitive adhesive is applied by applying a pressure-sensitive adhesive to the region surrounded by the frame portion formed in step S105 (second application step) and irradiating the applied pressure-sensitive adhesive with ultraviolet rays (second bonding step). A coating / curing process is executed (step S106).
At this time, since the frame portion of the pressure-sensitive adhesive is formed, it is possible to prevent the pressure-sensitive adhesive from spreading from the frame portion, and it is possible to apply the pressure-sensitive adhesive only in the region that becomes the active region.
In step S106, as in step S105, it is also possible to apply the adhesive using a normal dispenser 200 that does not have an irradiation head and cure the adhesive with a UV curing device.
As a result of the execution of step S106, the pressure-sensitive adhesive is applied to the entire surface only in the active area of the cover glass 120.

Then, in a vacuum atmosphere, the liquid crystal panel 110 completed in step S103 and the cover glass 120 coated with the adhesive in step S106 are bonded together in an aligned state (step S107) (placement process).
At this time, since the pressure-sensitive adhesive is cured by ultraviolet rays, the adhesive layer 130 can be easily disposed only in the active region without almost exuding from the active region.
As a result of step S107, the liquid crystal panel 110 and the cover glass 120 are bonded together while preventing the adhesive from being uncured.
Therefore, the liquid crystal panel 110 and the cover glass 120 can be bonded together more appropriately using the UV curable resin adhesive.
In addition, since the adhesive can be disposed on the entire surface of the active region, display unevenness can be suppressed and display quality can be improved.

(Third embodiment)
In the first embodiment, the case where the adhesive is disposed on the entire active region has been described as an example. However, in the present embodiment, the liquid crystal panel 110 and the cover glass 120 are bonded together using the entire active region as an air layer. .
FIG. 6 is a diagram illustrating a configuration of the electro-optical device 400 obtained by the manufacturing method according to the present embodiment.

In FIG. 6, the portions other than the adhesive layer 430 disposed between the liquid crystal panel 110 and the cover glass 120 have the same configuration as the respective portions shown in the electro-optical device 100 in the first embodiment.
The adhesive layers 430 are disposed at the four corners of the frame portion between the liquid crystal panel 110 and the cover glass 120, and are hidden from the viewing side by the black mask 120a.

Next, a method for manufacturing the electro-optical device 400 according to this embodiment will be described.
FIG. 7 is a flowchart showing a method for manufacturing the electro-optical device 400 according to this embodiment.
In FIG. 7, steps S201 to S203 for manufacturing the liquid crystal panel 110 are the same as the steps S1 to S3 in FIG. 2 of the first embodiment.
Apart from the steps S201 to S203, a glass substrate is prepared as a base material for the cover glass, and a function of limiting the viewing angle is provided by forming a slit or the like as necessary. Then, after the glass substrate is separated into pieces to form the cover glass 120, this is washed (step S204).

Next, an adhesive drawing process (application process) is performed by drawing (applying) the adhesive at the four corners of the region serving as the frame portion of the cover glass 120 (step S205).
Specifically, first, the cover glass 120 is detachably fixed to the surface plate 210, and the relative position between the syringe 220 and the cover glass 120 is adjusted using, for example, the alignment mark 121 (see FIG. 1A). . Further, an adhesive containing an epoxy resin having ultraviolet curing properties is stored inside the syringe 220. Then, the adhesive is discharged from the syringe 220 while changing the relative position between the cover glass 120 and the syringe 220, and the adhesive is drawn on the cover glass 120.

Here, an adhesive is applied to the four corners of the region to be the frame portion of the cover glass 120.
At this time, in a later step, the liquid crystal panel 110 and the cover glass 120 are in close contact with each other, and the adhesive oozes out between the bonded surfaces, or the adhesive oozes out from the active region or The adhesive is applied by subtracting the spread amount of the adhesive so that the adhesive does not flow out from the end.

Next, the liquid crystal panel 110 and the cover glass 120 are pressed together in a vacuum atmosphere in a state where they are aligned (step S206). As a result, the adhesive is spread between the liquid crystal panel 110 and the cover glass 120 to form the adhesive layer 430, and the liquid crystal panel 110 and the cover glass 120 are in close contact with each other due to the adhesiveness.
At this time, since the adhesive is applied by subtracting the spread amount of the adhesive as described above, the adhesive spread between the bonding surfaces is disposed only in the frame portion.

Next, in step S207, alignment is performed using the alignment marks 113 and 121 (arrangement step). In step S208, ultraviolet rays are irradiated from the upper surface side of the cover glass 120, and the ultraviolet rays are irradiated to the concave mirror (the concave mirror 308 in FIG. 4). And temporarily irradiating ultraviolet rays from the side surfaces of the liquid crystal panel 110 and the cover glass 120 to execute a temporary curing process.
In step S209, as in step S207, alignment is performed using the alignment marks 113 and 121. As a result, even when the adhesive layer 430 has undergone curing distortion by the temporary curing process in step S208, the positional deviation can be eliminated.

Next, in step S210, the liquid crystal panel 110 and the cover glass 120 are irradiated with ultraviolet rays to perform a main curing process (adhesion process).
In step S210, when the adhesive contains a thermosetting component, the thermosetting treatment is also performed to sufficiently cure the adhesive, and the liquid crystal panel 110, the cover glass 120, This is glued.
As described above, in the method of manufacturing the electro-optical device according to this embodiment, the entire active region is an air layer, adhesive layers are formed at the four corners outside the active region, and the liquid crystal panel 110 and the cover glass 120 side are formed. These are adhered by irradiating them with ultraviolet rays.

Therefore, a relatively small amount of adhesive is applied to a region near the edge of the liquid crystal panel 110 at the peripheral edge of the bonding surface, and this is cured by irradiating ultraviolet rays from the side. Occurrence can be suppressed.
Therefore, the liquid crystal panel 110 and the cover glass 120 can be bonded together more appropriately using an adhesive of UV curable resin.
Further, since the entire active region is an air layer, display unevenness can be suppressed and display quality can be improved.
Furthermore, since the liquid crystal panel 110 and the cover glass 120 are bonded at the four corners of the region hidden by the frame portion, the adhesive used for bonding can be reduced.

In the present embodiment, the case where the active region is an air layer has been described as an example using the manufacturing method of the first embodiment, but also when the manufacturing method of the second embodiment is used, The active area can be an air layer.
That is, in step S105 in the second embodiment, after the areas where the adhesive is applied and cured are the four corners of the area to be the frame portion of the cover glass 120, as in step S205 of the present embodiment (first The electro-optical device 400 using the pressure-sensitive adhesive can be obtained by bonding in the application step, the first bonding step) and the bonding in step S207 (placement step).
