1378305 IX. Description of the Invention: [Technical Field] The present invention relates to a liquid crystal display panel, and more particularly to a liquid crystal display panel including a column spacer. [Prior Art] In recent years, light, small, and high definition liquid crystal display devices have been developed in the field of information devices (especially computers) and video devices (especially televisions). In general, a liquid crystal display device includes a liquid crystal display panel having an array substrate, an opposite substrate, and a liquid crystal layer sandwiched between the array substrate and the opposite substrate. The array substrate and the opposite substrate each have a display area. For example, a plastic bead having a uniform particle size is disposed as a spacer between the array substrate and the opposite substrate to keep the gap between the substrates constant. The array substrate is bonded to the opposite substrate by a sealing member which is shaped like a rectangular frame and disposed outside the display area of each substrate. In a color display active matrix for driving a liquid crystal display device, a plurality of signal lines and a plurality of scanning lines are arranged in a matrix on an array substrate in a display area thereof. A thin film transistor (hereinafter referred to as D-FT) including a semiconductor layer made of, for example, amorphous germanium (a_si) or polycrystalline germanium (p_Si) is disposed between each of the lines and each scanning line One is near and some is nearby. The TFTs are connected to individual pixel electrodes formed on the substrate. An alignment film is deposited on the substrate and the pixel electrodes. In the counter substrate, a color filter-common electrode and an alignment film are sequentially formed in a substrate. The color data system consists of red, green and blue 135276.doc 1378305 color layers, respectively. The liquid crystal layer is sandwiched between the array substrate and the opposite substrate to form the liquid crystal display device. Further, for example, it is disclosed in Japanese Patent Application Laid-Open No. Hei. No. Hei. A technique of hooking a gap between an array substrate and an opposite substrate. Japanese Patent Application KOKAI Publication No. 2006_18238 discloses a technique of forming a columnar spacer on at least one of the array substrate and the opposite substrate by patterning using a photolithography method or the like.

The column spacer covers the common electrode. On the array substrate, the column spacer may also cover the pixel electrode, and the pixel electrode and the common electrode layer are formed of Tinkium (Indium Tin Oxide), which is an inorganic material. In this case, the pixel electrode is as brittle as the common electrode as glass. Therefore, when the column spacer covers the pixel electrode and the common electrode, the liquid crystal display panel cannot sufficiently absorb the impact after being subjected to the impact. Therefore, the common electrode or the like can be damaged. In addition, at low temperatures, the (tetra) crystal display panel does not

The volume change can be fully followed, resulting in a higher probability of bubble generation. This will degrade the display quality.

An interlayer insulating film 15 is formed on the gate insulating film 12, the scanning line 13, and the signal line 丨4. The interlayer insulating film 15 is formed of an organic resin which is one of organic materials. The interlayer insulating film 15 has a thickness of about 丨 to 4 μm. For example, 135276.doc TFT 16 is provided as a - (4) element near an intersection between each scan line 13 and each signal line 14. The 16 is electrically connected to the scan line ^ and the signal line 14. 〜6 has a gate electrode 16& 'which corresponds to an extension of one of the scanning lines I]; a channel layer 16b which is opposite to the gate via the gate insulating film 12, i, source A pole electrode (10) connected to the channel layer domain and a gate electrode 16d connected to another region. In this embodiment, the channel layer is formed of polycrystalline germanium (p-Si). The source and the electrode 16c are connected to the signal line 14. The electrodeless electrode 16d is connected to a pixel electrode 17 as described below. A plurality of pixel electrodes 17 are formed in a matrix on the interlayer insulating film 15. Each of the pixel electrodes 17 is formed of a transparent conductive film (for example, IT〇 (indium tin oxide). The inorganic material is connected. The pixel electrode 17 is connected to the drain electrode via a contact hole formed in one of the interlayer insulating films 15. The electrode 16 (1. The pixel is formed of the TFT 16, the pixel electrode 7 and the like. Although not all shown, a plurality of column spacers 5 are formed at a predetermined density on the interlayer insulating layer 5). The column spacers 5 are each covered with the interlayer insulating film 15 and positioned away from the pixel electrode 7. In the present embodiment, the column spacers 50 are positioned completely away from the pixel electrodes 17 and completely away from the pixel regions. The object 50 is formed of a transparent resin. One of the columnar spacers 5 一方 in a direction along the plane of the liquid crystal display panel has a rectangular shape. An alignment film 18 is formed on the glass substrate 11 to cover the pixels. Electrode 17 ° As shown in FIGS. 1 to 4 and 6, the opposite substrate 2 has a glass substrate as a transparent insulating substrate as 135276.doc 1378305. In the display region R1, a rubbing scanning line 13 is formed on the glass substrate 21. And signal line 丨4 The light blocking layer 31. The light blocking layer 31 forms a plurality of openings 32 in a matrix form. A peripheral photoresist layer 33 is formed on the glass substrate 21 outside the display region R1. The barrier layer 33 is entirely formed around the outer periphery of the display region R1 to help block light from leaking between the outside of the display region R1 and the inside of the bezel 3. A plurality of the light blocking layer 31 and the peripheral light blocking layer 33 are disposed. The color layer, that is, a plurality of red layers 40R, a plurality of green layers 4〇G, and a plurality of blue layers 40B are formed as an insulating layer formed of an organic material. The color layers 40R, 40G, and 40B are alternately arranged adjacent to each other. A color filter 4 is formed. The thickness of the color filter 40 is about 丨 to 4 μηη. The peripheral portions of the color layers 4〇R, 4〇〇, and 40B cover the photoresist layer 31. In the color layer 40R, 40G and 40B are provided with a common electrode 22 formed by a transparent conductive film (for example, ιτο). The common electrode 22 includes a plurality of penetration holes 22a. In the present embodiment, each of the penetration holes 22a covers the corresponding column. The spacer 50 forms the penetration hole 22a as a moment The through hole surrounds the column spacer 5G. Therefore, the position of the common electrode 22 is completely away from the column spacer 50. An alignment film 23 is formed on the glass substrate 21 on which the common electrode 22 is formed. 10 and the opposite substrate 2 are disposed opposite to each other with a columnar edge 5G separated therebetween. The substrate 1G and the opposite substrate 2 are joined by the sealing member 7? The sealing portion (4) is shaped like I35276.doc -13 - 1378305 and has the same rectangular frame and is arranged on the peripheral portion of the two substrates.

The liquid crystal layer 80 is sandwiched between the array substrate 1A and the opposite substrate 2A. A liquid crystal injection port 71 formed in a portion of the sealing member 7 is sealed with a sealing agent 72. A first polarizer 9 is located on one of the outer surfaces of the array substrate 1 . A second polarizer 92 is located on an outer surface of the opposite substrate 20. In the present embodiment, a display surface s is an outer surface of one of the second polarizers 92. As shown in Figs. 1 and 2, a backlight unit 2 is located on one outer surface side of the array substrate 1''. The backlight unit 2 has a light guide body 2a positioned opposite to the first polarizer 91, and a light source 2b and a reflector 2c located at one side edge of the light guide body opposite to the light guide body. The light guide body 2a has a light emitting surface S2 positioned opposite to the first polarizer 91. The bezel 3 is formed in a frame shape on the side of the display surface si and outside the display region R1. The collecting spot 3 is positioned such that an inner peripheral penetrating position thereof is opposed to the peripheral light blocking layer 33. The configuration of the liquid crystal display device and a method of manufacturing the liquid crystal display device will now be described in detail. As shown in Fig. 1 to Fig. 6F, 'the first step is to form a gate insulating film Η, sweeping the wire 1 line 14 on a glass substrate u which is made to be damaged by a positive process (for example, repeated deposition and patterning). Interlayer insulating films 丨 $, 6, pixel electrodes 17 and the like. The interlayer insulating film 15 is formed using an organic resin. Use IT〇 to form a pixel. Next, a photosensitive resin is applied, for example, on the entire surface of the glass substrate using a square applicator.

The transparent resin is dried after Ik. The transparent resin is exposed and thus patterned using a predetermined mask. The reticle used has a pattern required to form I35276.doc 1378305 column spacer 50. Next, the exposed transparent resin is developed and sintered and cured. As a result, a plurality of column spacers 50 are formed. Each of the columnar spacers 5 is formed away from the corresponding pixel electrode 17 (pixel region R2). Subsequently, an alignment film is coated on the glass substrate 包括 including the display region R1 to form an alignment film 18. In this embodiment, the alignment film 8 is a vertical alignment film. In other respects, in the method of manufacturing the counter substrate 20, the glass substrate 21 is first prepared. Next, a photoresist layer and a peripheral light blocking layer 33 are formed on the glass substrate 21, and then sequentially formed on the glass substrate 21, the light blocking layer 31, and the peripheral light blocking layer 33 by, for example, a photolithography method. Layer 40R. Subsequently, similar to the color layer 4R, the color layers 40G and 40B are formed using, for example, the photolithography method. Subsequently, the common electrode 22 is formed so as to cover the color layers 4?R, 4?G, and 40B. The formation of the common electrode 22 involves coating a layer of ITO on the glass substrate to deposit a layer of yttrium and then removing the ruthenium from the area opposite the column spacer 5 by photolithography. Thus, the common electrode 22 including a plurality of penetration holes 22a is formed. Next, the alignment film 23 is formed by coating an alignment film material on the glass substrate 21 including the display region. In the present embodiment, the alignment film 23 is a vertical alignment medium. Next, for example, an ultraviolet curable resin is applied along the periphery of the opposite substrate 20. Subsequently, the array substrate 10 and the opposite substrate 2 are disposed opposite to each other with a predetermined gap therebetween by the column spacers 50, thereby aligning the alignments 135276.doc 15 1378305 臈18 and 23 with each other. The array substrate 10 and the peripheral portion of the opposite substrate 20 are adhered together using an ultraviolet curable resin. Thereafter, the ultraviolet curable resin is irradiated with ultraviolet rays and thus cured. Thereby, the sealing member 70 which fixes the array substrate 10 and the opposite substrate 20 is formed. Thereafter, the array substrate 10 and the counter substrate 2 adhered together are placed in a vacuum chamber (not shown). Next, under a vacuum, a liquid crystal is injected through the liquid crystal injection port 71 through one of the array substrate 1 〇, the opposite substrate 2 〇, and the sealing member 7 。. Subsequently, the liquid crystal injection port 71 is sealed with a sealant 72 composed of, for example, an ultraviolet curable resin. Thereafter, the liquid crystal panel into which the liquid crystal is injected is carried away from the vacuum chamber. Next, the first polarizer 91 is positioned on the outer surface of the array substrate 10. The first polarizer 92 is positioned on the outer surface of the opposite substrate 20. Therefore, the liquid crystal display panel 1 in the one VA mode is formed. Next, on the liquid crystal display panel 1, the women's backlight unit 2, the bezel 3, and the like are assembled to assemble them into a module. Thereby a liquid crystal display device is completed. In the liquid crystal display device configured as described above, each of the column spacers 50 is positioned away from the pixel electrode 17 and the common electrode 22. Therefore, a plurality of penetration holes 22a are formed in the common electrode 22 on the side opposite to the substrate 2 so that the column spacers 50 cover the corresponding penetration holes 22a. Therefore, the position of the columnar spacer 5〇 can be away from the pixel electrode 17 and the common electrode 22 which are insufficient in elasticity. Further, since the penetration holes 22a are formed away from the corresponding pixel electrode 17 and the common electrode 22, the display is prevented from being affected. On the array substrate 10 side, a columnar spacer 50 is formed on the interlayer insulating film 15 formed of an organic resin. On the side of the opposite substrate 2, the column spacers 5 〇 I35276.doc 1378305 cover the color layers 40R, 40G, and 40B (color filters 4A) formed of an organic material. The components from the interlayer insulating film 15 to the color filter 4 are disposed in the following order in the direction perpendicular to the plane of the liquid crystal display panel 1: the interlayer insulating film 15, the column spacer 50, the alignment film 18, and the alignment film 23 And the color filter 40. Similar to the column spacer 50, the interlayer insulating film 15 and the color filter 4 are elastic. Therefore, when, for example, the temperature is low, it is applied to the liquid crystal display panel! One of the external impacts can be absorbed by the entire liquid crystal display panel i including the column spacers 5〇. Since the volume change is completely followed, possible bubbles (cavity portions) between the array substrate 丨〇 and the opposite substrate 20 can be suppressed. Therefore, an appropriate image can be displayed even under an external impact. Since the color filter 4 is provided on the opposite substrate 20 side, an external impact can be absorbed on the side of the array substrate and the side of the opposite substrate 20 without adding conventional manufacturing steps and components. As described above, a liquid crystal display device having high display quality can be obtained. A liquid crystal display device according to another embodiment of the present invention will now be described in detail. One of the configurations not described below in this embodiment is the same as in the above specific embodiment. The same reference numerals denote the same elements and detailed description thereof will be omitted. Although not shown in the drawings, the liquid crystal display device has the above liquid crystal display panel 1, the backlight unit 2, and the bezel 3. As shown in Fig. 7, the liquid crystal display panel 1 includes an array substrate 10, an opposite substrate 20, a color filter 40, a column spacer 50, and a liquid crystal layer 80. Although the liquid crystal display panel 1 is not shown in the drawing, the sealing member 70, the first polarizer 91, and the second polarizer 92 are also provided. The liquid day display panel 1 has a pixel pitch of 3 〇.〇 μπι. 135276.doc 1378305 As shown in Figs. 7 and 8, a resistive layer 31 and a peripheral light blocking layer 33 (not shown) are formed on the glass substrate 21 in the counter substrate 2A. The light blocking layers 31 are extended to form a strip or a grid. In this embodiment, the photoresist layers are formed in a grid shape. The light blocking layer 31 has a covering portion 31a and a non-covering portion 31b. The covering portion 31a covers the corresponding column spacer 5〇. The non-covered portion 3ib is located away from the braided spacer 50. The cover portion 31a and the non-cover portion 31b are disposed in the second direction d2. The width w1 of the covering portion 3 la is larger than the width w2 of the non-covering portion 31b. The peripheral portions of the color layers 40R, 40G, and 40B cover the light blocking layer 31. The color filter 40 has a portion 4a that is formed in a portion of the covering portion 31a. The slit portion 4A is rectangular and has a length of 6 μm in the first direction d1 and a length of 12 μηη in the second direction d2. In the covering portion 31a of the light blocking layer 31, the slit portion 4A is not covered with the color filter 40. That is, the covering portion 3丨3 is constituted by a slit portion 4〇a in which the color filter 40 is located and covers a portion of the light blocking layer 31 and in which the color filter 40 is not present and the light blocking layer 31 is exposed. On the other hand, the covering portion 31b of the light blocking layer 31 is completely covered by the color filter layer. An undercoat film 25 made of a transparent conductive material is formed on the light blocking layer 31 and the color layers 40R, 40G and 40B. The undercoat film 25 is used to planarize the opposite substrate 20 and protect the liquid crystal layer 80. A common electrode 22 is formed on the undercoat film 25. The common electrode 22 includes a plurality of through holes 22a. In the present embodiment, each of the penetration holes 22a covers the corresponding column spacer 50. The penetration holes 22a are formed in a strip shape and 135276.doc 18· 1378305 extends in the first direction d1. The penetration hole 22a has a width of 12 μm in the second direction d2. The position of the common electrode 22 is completely away from each of the column spacers 50» on the glass substrate 21 on which the common electrode 22 is formed to form the alignment film 23. Each of the column spacers 5 is formed on the array substrate 10. The column spacers 50 are positioned away from the corresponding pixel electrodes 17. The column spacer 5 is provided so as to cover the penetration hole 22a, the covering portion 31a, and the slit portion 40a. Further, in the slit portion 40a serving as the covering portion 31a of the base, the light blocking layer 31 is provided. There is no color filter used as a pillar and the light blocking layer 3 1 ' is thus exposed. Thus, the surface of one of the opposing substrates 20 on the slit portion 4A is sufficiently flattened by the undercoat film 25. That is, in a region covering one of the slit portions 4A, the distance between the array substrate 10 and the opposite substrate 20 is uniform, and the distance between the array substrate 10 and the opposite substrate 20 is uniform. Column spacer 50. The liquid crystal layer 80 contains a liquid crystal material having a negative dielectric anisotropy. In the liquid crystal display device configured as described above, each of the column spacers 50β is positioned away from the pixel electrode 丨7 and the common electrode 22 on the side of the opposite substrate 2, and a plurality of penetration holes 22a are formed in the common electrode 22 and A column spacer 5 is provided to cover the corresponding penetration hole 22a. Therefore, the columnar spacer 50 can be formed away from the pixel electrode 17 and the common electrode 22 which are insufficient in elasticity. Further, each of the penetration holes 22a is formed away from the corresponding pixel electrode 17 and the common electrode 22. This prevents the display from being affected. Further, the pixel electrode 17 and the common electrode 22 can be prevented from being damaged. Therefore, a possible defect can be prevented, one of which is caused by damage of any of the electrodes 135276.doc 19 1378305. The column spacer 50 is positioned away from the color filter 40 so as to cover the cover portion 3u and the slit portion 40a. The opposite substrate 2A covering the covering portions 31a has a uniform southness. One of the top end portions of the column spacer 50 may be brought into proper contact with the opposite substrate 20. Therefore, the elasticity of the column spacer 5〇 can be maximized with respect to one loading. Thus the shape of the column spacer 50 flexibly follows an external impact. Further, the gap between the array substrate 10 and the opposite substrate 20 can be held constant. This prevents a possible partial improper display due to a possible localized improper gap. In addition, one of the possible drops in transmittance (this is an optical feature) can be suppressed as a white display of yellowing and a possible uneven display. By providing the column spacers 5 相 on the opposite substrate 20 in a region where the size of the recesses and protrusions is not significantly changed, the variation of the cell gap in the batch can be reduced. Therefore, by using a liquid crystal dropping method on the right, the range of the dropping boundary can be increased. Therefore, a liquid crystal display device having a high product yield can be obtained. If the formed color filter 40 has no slit portion 40a, the peripheral portions of the color layers can be covered with each other, so that the size of the depressions and projections on the opposite substrate 2 can be significantly changed. In this case, the contact with the counter substrate 2 turns with the column spacer 50. Thereafter, some of the column spacers are always in contact with the opposite substrate while others are not in contact with the opposite substrate. Further, in this case, even if the undercoat film 25 is formed, sufficient planarization cannot be achieved. Therefore, the size of the depressions and protrusions on the opposite substrate 20 is significantly changed. Further, since the through hole 135276.doc • 20· 1378305 22a having a width of 12 μηΐ 2 is formed in the common electrode 22, the orientation state of the liquid crystal molecules is maintained, and the display of an excellent viewing angle characteristic is enabled. Therefore, the penetration hole 22a in the common electrode 22 controls the direction of the liquid crystal molecules in the liquid crystal layer 80. The shape of the penetration hole 22a should not be limited to a strip but may vary. For example, as shown by the circle 9, the penetration hole 22a may be rectangular. In this case, the penetration holes 22a in the common electrode 22 also control the direction of the liquid crystal molecules in the inclined liquid crystal layer 8, for example, as shown in Fig. 10, the penetration holes 22a may be hexagonal. In this case, the through-holes of the common electrode 22 also control the direction of the liquid crystal molecules in the inclined liquid crystal layer 80. Specifically, the through hole 22a in the & case is suitable for a liquid crystal display device in an MVA (Multi-Domain Vertical Alignment) mode. As described above, a liquid crystal display device having high display quality can be obtained. The invention is not limited to the specific embodiments described above. In the implementation, the components of the specific embodiments may be changed without departing from the spirit of the invention. Further, various inventions can be made by appropriately combining a plurality of components disclosed in the above specific embodiments. For example, some of the components of the components shown in the specific embodiments may be omitted. Moreover, the components of the different embodiments can be combined. For example, the shape of the columnar spacer 50 and the penetration hole 22a is not limited to the above-described specific embodiment, but may vary. "The column spacer 50 only has to be formed on either of the array substrate 10 and the opposite substrate 2". . The column spacers 5〇 do not have to be positioned completely away from the corresponding pixel electrodes 17. The column spacer 5 〇 partially covers the pixel electrode 17 . The column spacer 50 does not have to completely cover the corresponding penetration hole 22a. The column spacer 50 can be positioned to partially cover the common electrode 22. 135276.doc -21 - 1378305 Although it is not shown in the drawing 'If the color filter 4 is provided on the array substrate 10, the opposite substrate 20 may have an insulating layer which is opposite to the array substrate 20 with respect to the common electrode 22. It is positioned and laminated to the common electrode 22 and formed of an organic material. Therefore, a column spacer can be placed on the top of the insulating layer.
