Description

  The present invention relates to a liquid crystal display device, and more particularly to an active matrix type liquid crystal display device.

  In general, a liquid crystal display device includes a liquid crystal display panel including a display unit on which an image is displayed, and a backlight that illuminates the liquid crystal display panel. The liquid crystal display panel includes an array substrate and a counter substrate facing each other. A plurality of spacers are arranged so as to form a predetermined gap between the array substrate and the counter substrate. A liquid crystal layer is sandwiched between the array substrate and the counter substrate. In addition, the liquid crystal display device includes a display unit composed of display pixels arranged in a matrix and a peripheral unit surrounding the display unit.

  In the display portion, red, green, and blue colored layers (hereinafter referred to as a red layer, a green layer, and a blue layer) are arranged corresponding to each display pixel. In the peripheral portion, a light shielding layer is disposed for shielding backlight light transmitted between patterns of various wirings and built-in circuits, and for suppressing reflected light due to light outside the panel.

  Conventionally, in the above-described liquid crystal display panel, when the array substrate and the counter substrate are bonded together, the gap between the two substrates in the display portion and the gap between the two substrates in the peripheral portion are different from each other. In some cases, display failure may occur in the vicinity of the boundary.

To prevent this problem, the display area near the boundary between the display area and the peripheral area is suppressed by making the spacers arranged in the display area equal to the sum of the heights of the spacers and the light shielding layer. A display device has been proposed (see Patent Document 1).
Japanese Patent Laying-Open No. 2005-266011

  However, even if the spacers arranged in the display unit as in the above display device and the sum of the heights of the spacers arranged in the peripheral part and the light shielding layer are equal, the counter substrate in the peripheral part is caused by its own weight. In some cases, a desired gap cannot be formed in the vicinity of the boundary, resulting in display failure.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a liquid crystal display device with good display quality.

  A liquid crystal display device according to a first aspect of the present invention includes a display unit including a plurality of display pixels arranged in a matrix, the display unit including a liquid crystal layer sandwiched between a first substrate and a second substrate. A liquid crystal display device having a peripheral portion around the liquid crystal display device, wherein a predetermined gap is formed between the first substrate and the second substrate, and a density of the peripheral portion is higher than that of the display portion. A plurality of spacers arranged to be large are provided.

  According to the present invention, a liquid crystal display device with good display quality can be provided.

  Hereinafter, a liquid crystal display device and a manufacturing method thereof according to a first embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, the liquid crystal display device according to the first embodiment of the present invention includes a liquid crystal display panel 10 having a substantially rectangular flat plate shape. The liquid crystal display panel 10 has a pair of substrates facing each other, that is, an array substrate 12 and a counter substrate 14. A liquid crystal layer LQ is sandwiched between the array substrate 12 and the counter substrate 14.

  The liquid crystal display panel 10 includes a display unit 10A including a plurality of display pixels PX arranged in a matrix and a peripheral unit 10B around the display unit 10A.

  In the display unit 10A, a plurality of scanning lines SL are arranged along a row where a plurality of display pixels PX are arranged, and a plurality of signal lines DL are arranged along a column where the plurality of display pixels PX are arranged. Yes. The plurality of scanning lines SL are connected to the scanning line driving circuit CSL disposed in the peripheral portion 10B. The plurality of signal lines DL are connected to a signal line driving circuit CDL disposed in the peripheral portion 10B.

  As shown in FIGS. 1 and 2, each display pixel PX has a pixel switch SW made of, for example, a thin film transistor (TFT). The gate electrode of the pixel switch SW is connected to the corresponding scanning line SL (or formed integrally). The source electrode of the pixel switch SW is connected to the corresponding signal line DL (or formed integrally). The drain electrode of the pixel switch SW is connected to the pixel electrode PE arranged in each display pixel PX by a contact hole CH.

  The scanning lines SL are sequentially selected by the scanning line driving circuit CSL, and the image data output from the signal line driving circuit CDL is applied to the pixel electrode PE via the pixel switch SW connected to the selected scanning line SL. .

  As shown in FIGS. 3 and 4, in the display unit 10A, any one of the colored layers CF corresponding to the display pixels PX, that is, the red layer R, the green layer G, and the blue layer B is provided on the pixel switch SW and the like. Is arranged.

  The film thicknesses of the red layer R, the green layer G, and the blue layer B are greatly related to the color reproduction range that can be expressed by the liquid crystal display device and the panel transmittance (panel luminance), so that the specifications of each product are satisfied. The film thickness is designed. In the liquid crystal display device of the present embodiment, the red layer R, the green layer G, and the blue layer B have a film thickness of about 3 μm. On the colored layer CF, spacers SS are arranged corresponding to the positions where the signal lines DL and the auxiliary capacitance lines Cs overlap, and a predetermined gap is formed between the array substrate 12 and the counter substrate 14.

  On the other hand, as shown in FIG. 2, the auxiliary capacitance line Cs extending from the display unit and the dummy auxiliary capacitance line DCs extending substantially parallel to the auxiliary capacitance line Cs are arranged in the peripheral portion 10B. On the auxiliary capacitance line Cs and the dummy auxiliary capacitance line DCs, a signal line DL extending from the display unit 10A and a dummy signal line DDL extending substantially parallel to the signal line DL are arranged via an insulating layer. As shown in FIGS. 3 and 4, a black colored layer K and a dummy colored layer DG are disposed in the peripheral portion 10B.

  The colored layer K suppresses blocking of light incident from a backlight (not shown) disposed on the back side of the liquid crystal display panel 10 and reflection of external light. In the present embodiment, the thickness of the colored layer K is about 4 to 5 μm.

  The dummy colored layer DG is disposed in the vicinity of the display portion 10A of the peripheral portion 10B. On the dummy colored layer DG, the same spacer SS as that disposed on the display unit 10A is disposed. The spacer SS corresponds to the position in the display unit 10A corresponding to the position where the signal line DL (or dummy signal line DDL) extending from the display unit 10A and the auxiliary capacitance line Cs (or dummy auxiliary capacitance line DCs) extending from the display unit 10A overlap. The same spacer SS as in FIG. At this time, the spacers SS in the peripheral portion 10B are arranged at a higher density than in the display portion 10A.

  That is, as shown in FIGS. 2 to 4, the spacers SS are arranged so that the number of the spacers SS arranged per unit area is larger in the peripheral part 10B than in the display part 10A. Therefore, the pitch at which the spacers SS are arranged in the peripheral portion 10B is smaller than the pitch at which the spacers are arranged in the display portion 10A. In this embodiment, the pitch at which the spacers SS are arranged in the display unit 10A is 500 μm, and the pitch at which the spacers SS are arranged in the peripheral part 10B is 410 μm.

  A method for manufacturing the liquid crystal display device will be described. First, a first mother substrate that becomes a plurality of array substrates is manufactured. That is, an undercoat layer (not shown) made of silicon oxide (SiOx) and silicon nitride (SiNx) and an amorphous silicon (a-Si) layer are sequentially deposited on the first glass substrate.

  After that, the a-Si layer is polycrystallized by excimer laser annealing (ELA) to form a polysilicon film. Thereafter, the polysilicon film is patterned to form a part necessary for a semiconductor layer of the pixel switch SW and a built-in circuit such as the scanning line driving circuit CSL.

  Subsequently, silicon nitride (SiNx) or silicon oxide (SiOx) is formed as a gate insulating film (not shown) of the thin film transistor. Thereafter, a metal layer made of, for example, an alloy of molybdenum and tungsten is formed, and the metal layer is patterned. As a result, the scanning line SL, the auxiliary capacitance line Cs, the dummy auxiliary capacitance line DCs, and other signal bus wiring (not shown) are formed.

  Further, an interlayer insulating film L1 made of silicon nitride (SiNx) or silicon oxide (SiOx) is formed, and a metal layer made of, for example, a laminate of molybdenum, aluminum, and molybdenum is formed thereon and patterned. Thereby, the signal line DL, the source electrode and drain electrode of the pixel switch SW, the dummy signal line DDL, and the like are formed.

  Thereafter, the red layer R, the green layer G, and the blue layer B, which are display colors of the display pixels PX, are formed and patterned to form the colored layer CF. At this time, a colored layer, for example, a dummy colored layer DG made of the same material as the green layer G is also formed on the dummy auxiliary capacitance line DCs in the vicinity of the display unit 10A of the peripheral part 10B and the dummy signal line DDL. Further, when forming the colored layer CF, a contact hole (CH) penetrating to the drain electrode of the pixel switch SW is simultaneously formed.

  Thereafter, for example, a transparent conductive layer such as ITO (Indium Tin Oxide) is deposited and patterned to form a pixel electrode PE that is in contact with the pixel switch SW via the contact hole CH. Further, a colored layer K that is a light shielding layer is formed in the peripheral portion 10B.

  Thereafter, by forming and patterning an organic insulating film, a spacer SS is formed at the intersection of the signal line DL and the auxiliary capacitance line Cs in the display portion 10A, and the dummy signal line DDL is formed in the peripheral portion 10B. A spacer SS is formed at the intersection of (or the signal line DDL) and the dummy auxiliary capacitance line DCs (or auxiliary capacitance line DCs).

  At this time, the spacer SS is formed in the peripheral portion 10B so that the density at which the spacer SS is disposed is larger than that in the display portion 10A. In particular, in the first embodiment shown in FIGS. 2 to 4, the shape and size of the spacer SS arranged in the peripheral portion 10B is the same as the spacer SS in the display portion 10A, but the arrangement pitch is set in the display portion 10A. Smaller than. Through such a process, the first mother substrate is formed.

  Next, a second mother substrate (not shown) to be a plurality of counter substrates 14 is formed. That is, a transparent conductive layer such as ITO is deposited on the second glass substrate to form the counter electrode CE, thereby forming a second mother substrate. An alignment film (not shown) made of a polyimide (PI) film or the like is applied to each of the first mother substrate and the second mother substrate, and a rubbing process is performed. Further, after drawing a sealing material on at least one of these mother substrates and bonding the pair of substrates together, cleaving and liquid crystal injection are performed to complete the liquid crystal display panel 10. In addition, although subsequent polarizing plate sticking etc. are performed, description about subsequent processes is abbreviate | omitted here.

  As described above, in the liquid crystal display panel 10 of the liquid crystal display device according to the present embodiment, the spacers SS are arranged in the peripheral portion 10B near the display portion 10A at a higher density than in the display portion 10A. That is, the pitch at which the spacers SS are arranged in the peripheral part 10B is smaller than the pitch at which the spacers are arranged in the display part 10A. As a result, as shown in FIG. 4, it is possible to increase the support strength in the peripheral portion 10B, and to suppress the deflection of the counter substrate 14 in the peripheral portion 10B.

  Further, in the above embodiment, since the colored layer CF is disposed on the array substrate 12 side, the weight of the counter substrate 14 is more than the weight of the colored layer CF than the display device in which the colored layer CF is disposed on the counter substrate 14 side. The deflection of the counter substrate 14 can be effectively suppressed.

  Therefore, according to the liquid crystal display device according to the present embodiment, it is possible to improve the gap unevenness of the liquid crystal layer LQ in the vicinity of the boundary between the display unit 10A and the peripheral unit 10B, and the peripheral unit 10B in the display unit 10A. Display defects in the vicinity of the boundary can be suppressed.

  Here, as described above, the spacer SS is disposed on the intersection of the signal line DL (or dummy signal line DDL) and the auxiliary capacitance line DCs (or dummy auxiliary capacitance line DCs). In the case of the above-described configuration, two metal layers (that is, a metal layer such as the signal line DL and a metal layer such as the auxiliary capacitance line Cs) and a three-layer insulating film (that is, an undercoat) are provided below the spacer SS. Layer, gate insulating film, interlayer insulating film L1), and further a colored layer CF.

  In each of these layers, a difference in film thickness occurs in the plane of the array substrate 12. For example, when a film pressure difference of about 10% is generated in each of the two metal layers and the three insulating films arranged under the spacer SS, a film pressure difference of about 0.5 μm at maximum is generated. For this reason, there is a possibility that a gap difference of about 0.5 μm at maximum is generated in the liquid crystal layer LQ.

  At this time, as shown in FIGS. 5 and 6, it is desirable to form a notch NT in the auxiliary capacitance line Cs and the dummy auxiliary capacitance line DCs, and to arrange the spacer SS at a position overlapping the notch NT. As a result, the number of layers disposed under the spacer SS is reduced, so that the gap uniformity can be further improved as compared with the case shown in FIG.

  Even when the notch NT is formed in the signal line DL and the dummy signal line DDL, the gap uniformity can be improved as described above. Furthermore, it is desirable to form the respective cutouts NT at the intersections between the storage capacitor lines Cs and the signal lines DL, and to arrange the spacers SS at positions that overlap these cutouts NT. By doing so, the number of layers disposed under the spacer SS is further reduced, so that the gap uniformity can be improved more effectively.

  In the peripheral portion 10B, the amount of deformation of the spacer SS may be larger than that of the display portion 10A due to the weight of the counter substrate 14. Accordingly, as shown in FIGS. 7 and 8, in the display unit 10A, the spacer SS is arranged at a position overlapping the notch NT formed in the storage capacitor line Cs or the signal line DL, and in the peripheral unit 10B, the dummy signal line DDL. And the dummy auxiliary capacitance line DCs.

  That is, even if the height of the spacer SS itself is the same, the spacer SS is formed from the surface of the glass substrate by forming the layers disposed below the spacer SS so as to be larger in the peripheral portion 10B than in the display portion 10A. The peripheral portion 10B is higher than the display portion 10A in the height (the sum of the height of the spacer SS itself and the film thickness of each layer disposed below the spacer SS).

  As described above, when the spacers SS are arranged in the display portion 10A and the peripheral portion 10B, even if the deformation amount of the spacer SS arranged in the peripheral portion 10B is increased, the space between the array substrate 12 and the counter substrate 14 is increased. The gap uniformity can be improved.

  Next, a liquid crystal display device according to a second embodiment of the present invention will be described. As shown in FIGS. 9 and 10, the dummy colored layer DG is disposed in the peripheral portion 10B in the vicinity of the display portion 10A, and the spacer SS is disposed thereon as in the first embodiment. In the following description, the same components as those in the first embodiment are denoted by the same reference numerals and description thereof is omitted.

  Also in the liquid crystal display panel 10 of the liquid crystal display device according to the present embodiment, the spacers SS are arranged in the peripheral portion 10B in the vicinity of the display portion 10A at a higher density than in the display portion 10A. In the present embodiment, in the peripheral portion 10B, the spacers SS are arranged at the same pitch as in the display portion 10A. Here, the spacer SS disposed in the peripheral portion 10B is thicker than the spacer SS disposed in the display portion 10A. That is, the area where the spacer SS is in contact with the counter substrate 14 per unit area is larger in the peripheral portion 10B than in the display portion 10A.

  In the case of the present embodiment, the diameter of the spacer SS disposed in the display portion 10A is 16.5 μm, and the diameter of the spacer SS disposed in the peripheral portion 10B is 19.0 μm.

  As described above, by making the spacer SS arranged in the peripheral portion 10B thicker than the spacer SS arranged in the display portion 10A, the density of the spacer SS in the unit area becomes larger in the peripheral portion 10B than in the display portion 10A. . From this, the support strength in the peripheral part 10B increases, and the deflection | deviation by the dead weight of the opposing board | substrate 14 can be suppressed.

  Therefore, according to the liquid crystal display device according to the present embodiment, a uniform cell gap can be maintained in the vicinity of the boundary between the display portion 10A and the peripheral portion 10B, and a liquid crystal display device with good display quality can be provided.

  Next, a liquid crystal display device according to a third embodiment will be described. As shown in FIGS. 11 and 12, a dummy colored layer DG is disposed in the peripheral portion 10B near the display portion 10A, and a spacer SS is disposed thereon. This is the same as in the first and second embodiments described above. In the following description, the same components as those in the first embodiment are denoted by the same reference numerals and description thereof is omitted.

  Similarly to the liquid crystal display device according to the first embodiment, the liquid crystal display panel 10 of the liquid crystal display device according to the present embodiment also arranges the spacers SS in the peripheral portion 10B near the display portion 10A at a higher density than in the display portion 10A. . As shown in FIG. 11 and FIG. 12, in this embodiment, the spacer SS arranged at a position away from the display unit 10A in the peripheral part 10B is more opposite to the spacer SS arranged in the vicinity of the display part 10A. The area in contact with 14 is large. In other words, the spacer SS disposed in the peripheral portion 10B becomes thicker as it is separated from the display portion 10A.

  In this embodiment, the diameter of the spacer SS arranged in the vicinity of the display unit 10A in the peripheral part 10B is 16.5 μm, and the diameter of the spacer SS arranged in a position away from the display part in the peripheral part 10B is 20.0 μm. is there.

  The weight of the counter substrate 14 that each spacer SS has to support increases as the distance from the end of the liquid crystal display panel 10 increases, but as described above, the area where the spacer SS contacts the counter substrate 14 increases as the distance from the display unit 10A increases. By doing so, the support strength in the peripheral part 10B increases, and the deflection of the counter substrate 14 can be more effectively suppressed.

  Furthermore, by increasing the spacer SS as the distance from the display portion 10A increases as described above, the counter substrate 14 can be more effectively supported by the spacer SS disposed in the peripheral portion 10B, so that the dummy colored layer DG is disposed. Can be made smaller.

  Since the dummy colored layer DG is formed on the metal wiring, it does not transmit the backlight. However, for example, when the dummy colored layer DG is formed from the same layer as the green layer G, the external light incident on the liquid crystal display panel 10 is not transmitted. The reflection may cause the display unit 10A in the vicinity of the peripheral part 10B of the liquid crystal display panel 10 to appear greenish. Therefore, a liquid crystal display device with better display quality can be provided by reducing the range in which the dummy colored layer DG is disposed as described above.

  That is, according to the present embodiment, it is possible to provide a liquid crystal display device with good display quality as in the case of the first and second embodiments described above.

  Next, a liquid crystal display device according to a fourth embodiment will be described. As shown in FIGS. 13 and 14, the dummy colored layer DG is disposed in the peripheral portion 10B in the vicinity of the display portion 10A, and the spacer SS is disposed thereon. This is the same as in the first to third embodiments described above. In the following description, the same components as those in the first embodiment are denoted by the same reference numerals and description thereof is omitted.

  Similarly to the liquid crystal display device according to the first embodiment, the liquid crystal display panel 10 of the liquid crystal display device according to the present embodiment also arranges the spacers SS in the peripheral portion 10B near the display portion 10A at a higher density than in the display portion 10A. . As shown in FIGS. 13 and 14, the size of the spacer SS arranged in the peripheral portion 10B is the same as that in the display portion 10A. In the present embodiment, in the peripheral portion 10B, the spacers SS are arranged so that the density increases as the distance from the display portion 10A increases. That is, the number of spacers SS arranged per unit area of the peripheral part 10B is larger than the number of spacers SS arranged per unit area of the display part 10A.

  In the present embodiment, the number density of the spacers SS arranged in the display unit 10A is 1 / dot, and the number density of the spacers SS arranged in the peripheral part 10B is 1.5 / dot. Note that 1 dot refers to a red pixel, a green pixel, and a blue pixel, each of which is a single pixel.

  In the case of this embodiment as well, the same effects as those of the first embodiment can be obtained, and the display quality is high by reducing the range in which the dummy colored layer DG is disposed as in the above-described third embodiment. A liquid crystal display device can be provided.

  That is, according to the present invention, it is possible to provide a liquid crystal display device with good display quality by increasing the supporting strength in the peripheral portion 10B and suppressing the deflection of the counter substrate 14.

  Note that the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage.

  For example, in the above-described embodiment, the liquid crystal display device using the low-temperature polysilicon technology has been described. However, the present invention can also be applied to a liquid crystal display device using the amorphous silicon technology, and is applied to a liquid crystal display device using the alpha moss silicon technology. However, the same effect as that of the above embodiment can be obtained.

  Furthermore, although the dummy colored layer DG is a layer composed of the same layer as the green layer G, the same effect can be obtained even when formed from the same layer as the red layer R and the blue layer B.

  In addition, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, you may combine the component covering different embodiment suitably.
