Description

  In the present invention, a phase difference plate provided on an upper surface of a liquid crystal display panel changes linearly polarized light emitted from the liquid crystal display panel into two circularly polarized light whose rotational directions are reversed, and one circularly polarized light is incident on the right eye. The present invention relates to a manufacturing apparatus and a manufacturing method for a polarization type three-dimensional liquid crystal display device in which one circularly polarized light is incident on the left eye, and parallax is generated in an image incident on the right eye and the left eye so as to perform stereoscopic display.

  In the polarizing glasses type three-dimensional liquid crystal display device, a phase difference plate 50 is provided on the front surface of the liquid crystal display panel 47 as shown in FIG. FIG. 11 is a production flow diagram of the phase difference plate 50, FIG. 12 is a plan view of the liquid crystal display panel 47, FIG. 13 is a plan view of the phase difference plate 50, and FIGS. It is the figure which bonded the liquid crystal display panel 47 and the phase difference plate 50 together. In the liquid crystal display panel 47, first, a polarizing plate 42 is disposed on the front surface of the backlight 41. Next, an array substrate 43 is disposed in front of the polarizing plate 42, and a liquid crystal material 44 is sealed between the array substrate 43 and a color filter substrate 45 provided in front of the array substrate 43. A polarizing plate 46 is disposed on the front surface of the color filter substrate 45, and a liquid crystal display panel 47 as shown in FIG. 12 is configured. Thus, since the polarizing plate 46 is provided on the outermost surface of the liquid crystal display panel 47, the light emitted from the liquid crystal display panel 47 becomes linearly polarized light 61.

  Next, the phase difference plate 50 will be described. As shown in FIG. 11, when manufacturing the phase difference plate 50, first, an alignment film is apply | coated on a base material and it is made to dry. Next, the alignment film that has been exposed and exposed by the exposure device is aligned. Thereafter, the phase difference plate 50 is manufactured by applying liquid crystal, drying, and UV-curing. The phase difference plate 50 is designed so that the phase difference is ¼ wavelength of the light wavelength. The optical axis of the phase difference plate 50 is an angle of 45 degrees with respect to the polarization axis of the polarizing plate 46. It is arranged in front of the liquid crystal display panel 47 so that Thus, the linearly polarized light 61 emitted from the liquid crystal display panel 47 becomes circularly polarized light due to the birefringence effect when passing through the phase difference plate 50.

  In the pixel of the liquid crystal display panel 47, a right-eye pixel line and a left-eye pixel line are alternately arranged for each scanning line. The right-eye pixel is a right-eye image, and the left-eye pixel is a left-eye pixel. A parallax image is displayed so as to be an image. Further, as shown in FIG. 13, the retardation plate 50 has two regions, a right-eye polarizing unit 48 and a left-eye polarizing unit 49, and the optical axis of the right-eye polarizing unit 48 is, for example, that of the polarizing plate 46. It is designed so that the polarization axis is +45 degrees and the optical axis of the left-eye polarization unit 49 is −45 degrees with respect to the polarization axis of the polarizing plate 46. As shown in FIG. 15, the right-eye pixel line of the liquid crystal display panel 47 is in the right-eye polarization unit 48 of the retardation plate 50, and the left-eye pixel line of the liquid crystal display panel 47 is in the left-eye polarization unit 49 of the retardation plate 50. The liquid crystal display panel 47 and the phase difference plate 50 are bonded so as to overlap each other. As a result, as shown in FIGS. 10B and 10C, the light that has passed through the phase difference plate 50 becomes, for example, the right circularly polarized light 62 in the right eye polarizing unit 48 and the left circularly polarized light in the left eye polarizing unit 49. 63. That is, the directions of the polarized light 62 emitted from the right-eye pixel and the polarized light 63 emitted from the left-eye pixel are reversed.

  On the other hand, in order to visually recognize these polarized lights, as shown in FIG. 10A, glasses 53 worn by an observer also have polarization characteristics. The glasses 53 are provided with a polarizing plate and a retardation plate (¼ wavelength plate), and the polarization characteristics of the right eye 51 and the left eye 52 are different. For example, a polarizing plate and a quarter-wave plate are arranged for the right-eye 51 so as to change the right circularly polarized light to linearly polarized light, and the left-eye 52 is used for changing the left circularly polarized light to linearly polarized light. A quarter-wave plate is arranged. When the observer wearing the glasses 53 visually recognizes the liquid crystal display panel 47 described above, the right circularly polarized light 62 emitted from the right-eye pixel is changed to linearly polarized light in the right-eye 51 of the glasses 53 and is thus observed in the right eye of the observer. Although it is incident, the left circularly polarized light 63 emitted from the left-eye pixel does not pass through the right-eye 51 of the glasses 53. Further, the left circularly polarized light 63 emitted from the left eye pixel is changed into linearly polarized light in the left eye 52 of the glasses 53 and is incident on the left eye of the observer, but the right circularly polarized light 62 emitted from the right eye pixel is the left eye of the glasses 53. Do not pass through 52. Therefore, the right eye sees a right eye image that is a set of right eye pixels, and the left eye sees a left eye image that is a set of left eye pixels. As described above, a parallax image is displayed on the liquid crystal display panel 47. Therefore, the observer can visually recognize the stereoscopic image.

  Various techniques have been proposed to realize the retardation plate as described above. First, Patent Document 1 discloses that a plurality of piece-like phase difference members are arranged adjacent to each other, and the slow axis or the fast axis of adjacent piece-like phase difference members are directed in different directions. . This piece-like phase difference member has a certain width, and phase difference regions composed of different slow axes or fast axes are regularly arranged. In addition, the phase difference is designed to be a quarter wavelength of light, and the slow axis and the fast axis are ± 45 degrees with respect to the polarization axis of the polarizing plate on the liquid crystal display panel. Designed to be at an angle. Thereby, the linearly polarized light emitted from the polarizing plate on the liquid crystal display panel changes into right circularly polarized light and left circularly polarized light when passing through the flaky phase difference member. A plurality of piece-like phase difference members and a liquid crystal display panel are bonded to each other, and a phase difference region composed of different slow axes or fast axes is displayed in advance alternately for the right eye and the left eye for each scanning line. If it corresponds to each scanning line of the liquid crystal display panel, the polarization direction emitted from the right-eye pixel and the polarization direction emitted from the left-eye pixel are different from each other. As a result, when viewing the liquid crystal display panel with polarized glasses, the right eye can see the right eye image and the left eye can see the left eye image. Can be displayed.

  Patent Document 2 discloses a retardation plate in which a fine periodic structure in which two regions having different optical axis directions of transmitted light are alternately formed is directly formed on a substrate. This fine periodic structure utilizes the fact that birefringence characteristics are generated when a plurality of flat plates having different refractive indexes, which originally do not have birefringence characteristics, are arranged with a period sufficiently smaller than the wavelength of light. The direction of the optical axis can be arbitrarily determined according to the direction in which the flat plates are arranged, and the direction parallel to the flat plate is the slow axis, and the direction perpendicular to the flat plate is the fast axis. Thereby, two areas having different optical axes can be alternately formed on one substrate. Further, depending on the material and design value of the fine periodic structure, the phase difference of each region is set to ¼ wavelength of the wavelength of light so that the optical axes of each region are orthogonal. The two regions are a right-eye polarizing unit and a left-eye polarizing unit, the right-eye polarizing unit overlaps the right-eye image of the liquid crystal display panel, and the left-eye polarizing unit overlaps the left-eye image of the liquid crystal display panel. The phase difference plate and the liquid crystal display panel are bonded so that the optical axes of the two regions are at an angle of ± 45 degrees with respect to the polarization axis of the polarizing plate on the liquid crystal display panel. Thus, when the linearly polarized light emitted from the polarizing plate on the liquid crystal display panel passes through the phase difference plate, it changes into right circularly polarized light and left circularly polarized light, and when an image displayed on the liquid crystal display panel is observed through polarizing glasses, The light from the right-eye pixel does not reach the left eye and reaches only the right eye, the light from the left-eye pixel does not reach the right eye and reaches only the left eye, and if a parallax image is displayed on the liquid crystal display panel 3D display.

  However, in both Patent Documents 1 and 2, by bonding the produced retardation plate and the liquid crystal display panel, the right-eye polarizing portion of the retardation plate overlaps the right-eye pixel line of the scanning line of the liquid crystal display panel, The left-eye polarizing part of the retardation plate overlaps the left-eye pixel line of the scanning line of the liquid crystal display panel. If the overlay accuracy is poor, the right-eye image and the left-eye image cannot be correctly recognized, and it is difficult for the observer to visually recognize the stereoscopic image.

Based on the detection results, the mask heads 2a and 2b are detected. Since the exposure position is corrected by following the pixel line, the right-eye polarizing portion 12a of the retardation layer 71 is accurately placed on the right-eye pixel 11a, and the left-eye polarizing portion 12b of the retardation layer 71 is accurately placed on the left-eye pixel 11b. Can be stacked. In this way, since the overlapping accuracy of the pixel and the phase difference region is good, if the parallax image is displayed so that the right-eye pixel is the right-eye image and the left-eye pixel is the left-eye image, the right-eye image The left-eye image can be correctly recognized, and the observer can recognize the stereoscopic image.

Then, the alignment layer 35 is exposed with the exposure light 37 emitted from the exposure light source 36 in the above-described manufacturing apparatus of the three-dimensional liquid crystal display device, thereby forming the retardation layer 71 on the liquid crystal display panel 1. A three-dimensional liquid crystal display device 72 is manufactured by forming a non-glossy film or a low reflection film 39 on the retardation layer 71. That is, the liquid crystal polymer coating step after exposure is omitted as compared with the first embodiment of the present invention.

  In the second embodiment, as described above, since the liquid crystal polymer is not applied after the exposure, the number of steps can be reduced, and the production efficiency in the manufacturing process of the three-dimensional liquid crystal display device 72 can be improved.

  Next, a third embodiment of the present invention will be described with reference to FIG. FIG. 5 is a diagram showing a manufacturing process of the three-dimensional liquid crystal display device according to this embodiment.

  As shown in FIG. 5, the liquid crystal display panel 1 includes a liquid crystal panel 31 having a plurality of black matrices 32 and a polarizing plate 33 provided on the upper surface of the liquid crystal panel 31. Then, an alignment film 35 is directly applied on the liquid crystal display panel 1. And the alignment film 35 is exposed using the manufacturing apparatus of the three-dimensional liquid crystal display device mentioned above. Thereafter, if the liquid crystal polymer 38 is applied onto the alignment film 35, a liquid crystal film is formed, and the right-eye polarizing portion and the left-eye polarizing portion of the retardation layer 71 are formed on the liquid crystal display panel 1. A three-dimensional liquid crystal display device 72 is manufactured by forming the non-glossy film or the low reflection film 39 on the retardation layer 71. That is, the process of sticking the base material to the liquid crystal display panel 1 is omitted as compared with the first and second embodiments of the present invention.

Further, in the third embodiment, since the base material is not used for forming the retardation layer, the material cost of the base material can be reduced.

  The photomasks of the two exposure apparatuses in the three-dimensional liquid crystal display manufacturing apparatus described above each have an opening having a size corresponding to the pixel line. First, the exposure device 30a exposes a portion corresponding to the right-eye pixel 11a in the alignment film to form the right-eye polarizing portion 12a, and then the exposure device 30b exposes a portion corresponding to the left-eye pixel 11b in the alignment film. Thus, the left-eye pixel region 12b is formed. In other words, the two exposure devices are exposed by a photomask having openings corresponding to different pixel lines, whereby different polarization portions are alternately formed for each pixel line.

  Next, a 3D liquid crystal display manufacturing apparatus according to a fourth embodiment of the present invention will be described. 6 to 9 are plan views showing an apparatus for manufacturing a three-dimensional liquid crystal display device according to a fourth embodiment of the present invention. As shown in FIG. 6, in the fourth embodiment of the present invention, the liquid crystal display panel 1 attracted and fixed to the stage of the transport unit 8 is transported in one direction by the transport unit 8 and in the opposite direction of this one direction. The At the front end of the liquid crystal display panel 1 in the conveyance direction (one direction), alignment marks 9 are formed in advance at both ends in the direction perpendicular to the one direction, and the liquid crystal display panel 1 is conveyed in the conveyance direction (one direction). The alignment mark 9 is also formed in advance at both ends in the direction perpendicular to the one direction at the rear end of the direction. The plate alignment camera 25 disposed above the transport unit 8 detects these alignment marks 9 in order to detect the position of the liquid crystal display panel 1. Based on the detection result, the adjustment unit adjusts the stage of the conveyance unit 8 to adjust the position of the liquid crystal display panel 1 as appropriate.

  One exposure device 30 a is installed above the transport area of the liquid crystal display panel 1. The photomask 3a of the exposure apparatus 30a extends in a direction perpendicular to the one direction and parallel to the surface of the liquid crystal display panel 1 so as to cover the entire region in the direction perpendicular to the transport direction (one direction) in the liquid crystal display panel 1. Exist. Openings 7a having a size corresponding to each pixel line of the liquid crystal display panel 1 are formed in the photomask 3a, and the openings 7a are provided at a pitch twice the arrangement pitch of the pixel lines. . That is, the opening 7a is provided at a position corresponding to every other pixel line, and as described later, the photomask 3a is shifted in the direction perpendicular to the one direction by the adjusting unit, thereby opening 7a. However, the liquid crystal display panel 1 can be moved to positions corresponding to the right-eye pixel line and the left-eye pixel line, respectively. The adjustment unit adjusts the position of the photomask 3a in alignment with the pixel line of the liquid crystal display panel 1 with the alignment mark 9 of the liquid crystal display panel 1 as a reference, and the photomask 3a is in a direction perpendicular to the one direction. Is moved by one pixel line. The alignment film on the liquid crystal display panel 1 is irradiated with right-eye polarized exposure light or left-eye polarized exposure light 27a from the exposure light source 26a through the opening 7a. As described above, this embodiment is different from the first embodiment in that there is one exposure apparatus and the adjustment unit moves (shifts) the photomask in a direction perpendicular to one direction. Since the configuration of the other exposure apparatus 30a is the same as that of the exposure apparatus 30a in the first embodiment, the description of the same part is omitted.

  Further, the control unit in the present embodiment irradiates the alignment film with the exposure light of polarized light for the right eye through the photomask 3a while transporting the liquid crystal display panel 1 in the one direction by the transport unit 8, and then transports the alignment film. Then, the conveyance by the unit 8 is stopped, and then the position of the photomask 3a of the exposure apparatus 30a is moved by one pixel line in the direction perpendicular to the one direction by the adjustment unit. The display panel 1 is controlled so as to irradiate the alignment film with polarized-eye exposure light for the left eye through the photomask 3a while transporting the display panel 1 in the direction opposite to the one direction. Note that the control unit in the present embodiment first irradiates polarized eye exposure light for the right eye, then irradiates polarized eye exposure light for the left eye, first irradiates polarized eye exposure light for the left eye, and then for the right eye. You may irradiate the exposure light of the polarized light.

  The operation of this embodiment will be described below. First, as shown in FIG. 6, the liquid crystal display panel 1 is transported by the transport unit 8 so as to reach the lower side of the exposure apparatus 30a. At this time, the plate alignment camera 25 detects the alignment marks 9 provided at the four corners of the liquid crystal display panel 1 to detect the position of the liquid crystal display panel 1. Based on the detection result, the position of the liquid crystal display panel 1 is appropriately adjusted. Then, the exposure device 30a follows the pixel line so that the opening 7a is accurately positioned above the right-eye pixel 11a of the liquid crystal display panel 1, and as shown in FIG. In the liquid crystal display panel 1 conveyed to (shown by the white arrow in FIG. 7), the exposure light source 26a of the exposure device 30a exposes the portion corresponding to the right-eye pixel 11a in the alignment film, thereby polarizing the right-eye polarizing unit. 12a is formed.

  Then, as shown in FIG. 8, after the right-eye polarizing portion 12a is formed in all the portions corresponding to the right-eye pixels 11a in the alignment film of the liquid crystal display panel 1, a photo is formed above the left-eye pixels 11b of the liquid crystal display panel 1. The adjustment unit moves the photomask 3a of the exposure apparatus 30a by one pixel line in a direction perpendicular to the one direction so that the opening 7a of the mask 3a is positioned. Thereafter, as shown in FIG. 9, the liquid crystal display panel 1 is transported in a direction (indicated by a white arrow in FIG. 9) opposite to the transport direction when the right-eye polarizing portion 12a is formed, and exposure light is emitted from the exposure light source 26a. Are switched to exposure light with polarized light for the left eye and emitted. As a result, the liquid crystal display panel 1 being conveyed is exposed through the photomask 3a to the portion corresponding to the left-eye pixel 11b in the alignment film, thereby forming the left-eye polarizing portion 12b. In the present embodiment, after the right-eye polarizing portion 12a is formed, the photomask 3a is moved (shifted) by one pixel line, but the stage on which the liquid crystal display panel 1 is attracted and fixed is moved (shifted). By doing so, the liquid crystal display panel 1 may be moved (shifted) by one pixel line. Furthermore, both the photomask 3a and the liquid crystal display panel 1 may be moved. As a result, the photomask 3a and the liquid crystal display panel 1 are relatively moved in a direction perpendicular to the one direction by one pixel line. You can do it.

  In the fourth embodiment, since the right-eye polarizing unit 12a and the left-eye polarizing unit 12b are formed by one exposure apparatus, the cost of the exposure apparatus can be reduced and the entire apparatus can be downsized.

  Note that the photomask of the exposure apparatus in the three-dimensional liquid crystal display manufacturing apparatus of each of the above embodiments has an opening having a size corresponding to the pixel line. First, the exposure device 30a exposes the portion of the alignment film corresponding to the right-eye pixel 11a to form the right-eye polarizing portion 12a, and then the exposure device 30a is perpendicular to the transport direction of the liquid crystal display panel 1 by one pixel line. The portion corresponding to the left-eye pixel 11b in the alignment film is exposed to form the left-eye pixel region 12b. In other words, one exposure apparatus sequentially exposes the alignment film corresponding to the right-eye pixel and the left-eye pixel with a photomask having an opening having a size corresponding to the pixel line. A polarizing part is formed.

  However, the present invention is not limited to the first to fourth embodiments, and for example, the photomask 3a of the exposure apparatus 30a has openings 7a having a size corresponding to every other pixel line, The photomask 3b of the exposure apparatus 30b may have one opening that extends the entire length in the width direction of the pixel region. In this case, the exposure light of the exposure device 30b exposes the entire alignment film 35 as the liquid crystal display panel 1 moves. With this configuration, first, the exposure device 30a exposes the portion corresponding to the right-eye pixel 11a in the alignment film to form the right-eye polarization unit 12a, and then the exposure device 30b applies to both the right-eye pixel 11a and the left-eye pixel 11b. The corresponding alignment film is exposed. At this time, if the energy of the exposure light of the exposure device 30b is low energy that does not consider the polarization direction of the right-eye polarization unit 12a that has already been formed, it is formed in the portion corresponding to the right-eye pixel 11a in the alignment film. The left-eye polarizing portion 12b is formed only in the region of the alignment film 35 corresponding to the left-eye pixel 11b, while the right-eye polarizing portion 12a is left as it is.

  Further, for example, the photomask 3a of the exposure apparatus 30a has one opening corresponding to the entire width direction of the pixel region, and the entire alignment film 35 is exposed by the exposure apparatus 30a by moving the liquid crystal display panel 1. The photomask 3b of the exposure device 30b has an opening 7b having a size corresponding to every other pixel line, and the exposure light of the exposure device 30b corresponds to the pixel line for the left eye. You may make it expose the area | region of the alignment film to perform. With this configuration, the exposure device 30a first exposes the entire alignment film 35, and then the exposure device 30b exposes only the portion corresponding to the left-eye pixel 11b in the alignment film. At this time, the energy of the exposure light of the exposure device 30b is sufficient to change the alignment film portion that has already been exposed by the exposure device 30a and becomes the polarization portion for the right eye to the polarization direction for the left eye In the exposure apparatus 30b, the alignment film region corresponding to the pixel line for the left eye becomes the polarizing portion for the left eye. Thereby, the left-eye polarizing portion 12b is formed in the portion corresponding to the left-eye pixel 11b in the alignment film, and the right-eye pixel 11a is not exposed to the right-eye pixel 11a that is not exposed by the exposure light of the exposure device 30b. The polarizing portion 12a for use remains. In the present invention, the right-eye polarizing section and the left-eye polarizing section formed on the liquid crystal display panel may be a circular polarizing section or a linear polarizing section.
