Description

  The present invention relates to a liquid crystal display device, and more particularly to a liquid crystal display device that takes measures against light leakage of a backlight from the periphery of a display area when black display is performed.

  In a liquid crystal display panel used for a liquid crystal display device, a pixel substrate and a TFT substrate in which pixels having thin film transistors (TFTs) and the like are formed in a matrix and a location corresponding to the pixel electrode of the TFT substrate facing the TFT substrate A counter substrate on which a color filter or the like is formed is disposed, and a liquid crystal is sandwiched between the TFT substrate and the counter substrate. An image is formed by controlling the light transmittance of the liquid crystal molecules for each pixel.

  In a liquid crystal display panel, liquid crystal exists in a region surrounded by a TFT substrate, a counter substrate, and a peripheral sealing material. There is a method of dropping liquid crystal instead of injecting liquid crystal into this space. In this method, a sealing material is formed at a predetermined position on the counter substrate, liquid crystal is dropped on the inside surrounded by the sealing material, and then the counter electrode and the TFT substrate are bonded together, followed by heating to cure the sealing material. Then, the counter substrate and the TFT substrate are completely bonded.

  In the liquid crystal dripping method, the sealing material is in a semi-cured state before the counter substrate and the TFT substrate are completely bonded, so the liquid crystal is inserted between the sealing material and the TFT substrate or the counter substrate, and the reliability of the seal portion is impaired. May be. In “Patent Document 1”, in order to improve the reliability of the seal portion in such a configuration, a configuration is described in which a spacer formed of resin is disposed in the seal portion together with the seal material.

  In the liquid crystal display device, an upper polarizing plate and a lower polarizing plate are attached to a liquid crystal display panel, a backlight is disposed on the back of the liquid crystal display panel, and the whole is protected by a frame. In order to increase the production efficiency of the liquid crystal display panel, a large number of liquid crystal display panels are formed on the mother substrate, and then the individual liquid crystal display panels are separated from the mother substrate by scribing.

  In order to prevent the sealing material from being crushed and sticking out of the display area when the mother TFT substrate formed with a large number of TFT substrates and the mother counter substrate formed with a large number of counter substrates are bonded together, It is necessary to increase the distance between the ends of the TFT substrate or the counter substrate, that is, a so-called frame region, in view of the tolerance. In “Patent Document 2”, a technique is described in which a groove portion is formed of resin and a sealing material is filled and bonded to the groove portion in order to reduce the frame region. In “Patent Document 2”, when each liquid crystal display panel is separated from the mother substrate, a region including a resin portion is scribed.

  FIG. 9 is a plan view of the liquid crystal display device. In FIG. 9, the display area substantially coincides with the area of the upper polarizing plate 11. The periphery of the display area is covered with a frame 200. Between the inner edge of the frame 200 and the edge of the display area is a peripheral area 12. A driving IC 350 is disposed on the liquid crystal display panel, and the driving IC 350 is connected to the flexible wiring board 400 attached to the liquid crystal display panel.

  10 is a cross-sectional view taken along the line DD of FIG. In FIG. 10, the TFT substrate 10 and the counter substrate 20 are bonded together by a sealing material 30 formed in the periphery. In FIG. 10, the black matrix 50 is formed so as to overlap the sealing material 30. An upper polarizing plate 11 is disposed on the counter substrate 20, and a lower polarizing plate 21 is disposed below the TFT substrate 10. The liquid crystal display panel is placed on a step formed inside the resin mold 300 via a light shielding tape 51.

  In FIG. 10, a backlight 100 is disposed on the back surface of the liquid crystal display panel. The backlight 100 includes a light guide plate 110, a reflection sheet 120, an optical sheet group 130, and a light source such as an LED (not shown) disposed on the side surface of the light guide plate 110. The optical sheet group 130 includes, for example, a diffusion sheet, a prism sheet, and the like. The backlight 100 is accommodated in the resin mold 300. The liquid crystal display device forms an image by controlling the light from the backlight 100 for each pixel.

  In FIG. 9, in the conventional structure, a phenomenon occurs in which light from the backlight 100 leaks to the peripheral region 12 when black is displayed. This is a factor that degrades the image quality. It is considered that light leakage from the peripheral region 12 is caused by the cause as shown in FIG.

  In FIG. 11, the TFT substrate 10 and the counter substrate 20 are bonded via a sealing material 30. The black matrix 50 formed on the counter substrate 20 exists in a region beyond the sealing material 30. However. The black matrix 50 cannot be formed up to the end of the counter substrate 20. This is because the black matrix 50 is easily peeled off at the end portion of the counter substrate 20, thereby reducing the reliability of the seal portion.

  The sealing material 30 is formed on the inner side of the end portion of the counter substrate 20 or the TFT substrate 10. This is to ensure a scribing area when separating each liquid crystal display panel from the mother substrate. FIG. 12 is a cross-sectional view showing the relationship between the scribe line 15 and the sealing material 30.

  In FIG. 12, the boundary between two liquid crystal display panels is a scribe line 15. The scribe line 15 is formed in the middle of the sealing material 30 of the adjacent liquid crystal display panel. In order to perform scribing stably in this part, the sealing material 30 is not formed in the part where scribing is formed. The distance d from the scribe line 15 to the end of the sealing material 30 is about 0.2 mm in consideration of the scribing accuracy. Accordingly, in FIG. 12, the BM is formed slightly to the end side of the substrate from the sealing material 30, but this amount is slight, and the distance from the BM end to the substrate end is also considered as d. Good. Therefore, after cutting along the scribe line 15, both the TFT substrate 10 and the counter substrate 20 have a transparent portion of only about 0.2 mm of glass.

  Returning to FIG. 11, part of the light incident on the TFT substrate 10 from the light guide plate 110 (not shown) repeats total reflection on the TFT substrate 10 and reaches the side surface of the TFT substrate 10. Therefore, the light is totally reflected and travels toward the counter substrate 20 side. The light reaching the upper end face of the TFT substrate 10 may be directed toward the counter substrate 20 or may be totally reflected on the surface of the TFT substrate 10.

  Whether or not the light is totally reflected depends on the incident angle of light. That is, assuming that the refractive index of the TFT substrate 10 is n1, the refractive index of air is n2, the incident angle of light with respect to the normal of the interface is θ1, and the outgoing angle of light is θ2, n1 / n2 = sin θ2 according to Snell's law. The relationship of / sin θ2 is established. When the refractive index of glass is 1.6 and the refractive index of air is 1, total reflection occurs when the incident angle θ1 of the light reflected from the TFT substrate 10 at the interface of the TFT substrate 10 is 40 degrees or more.

  However, if the incident angle θ1 is 40 degrees or less, light is emitted from the upper interface of the TFT substrate 10 toward the counter substrate 20. In this case, when the emission angle is small, it is blocked by the flange of the frame 200 and is not emitted to the outside. However, light having a certain range of emission angles emerges from the peripheral region 12 to the surface side of the counter substrate 20. Since this light has a bright outline especially in black display, it makes the impression of the screen worse.

  An object of the present invention is to prevent light leakage from the periphery of the display area as described above and to realize a display device with high image quality.

  The present invention overcomes the above problems, and specific means are as follows. That is, the sealing material for bonding the TFT substrate and the counter substrate is black, and the black sealing material is formed at least at the end of the counter substrate. Thereby, in the periphery of the TFT substrate, light directed toward the counter substrate can be completely blocked at the side surface of the TFT substrate and in the vicinity thereof.

  In this case, in order to perform scribing stably, the thickness of the sealing material is reduced on the scribe line. The thickness of the sealing material on the scribe line is 1 μm or more and 3 μm or less. In order to reduce the thickness of the sealing material on the scribe line, a cut portion spacer made of resin is formed on the scribe line.

  The cutting portion spacer is simultaneously formed of the same material as the columnar spacer that defines the distance between the TFT substrate and the counter substrate in the display region. On the scribe line, for example, there is only an overcoat film below the cut portion spacer, and in the display area, for example, an overcoat film and a black matrix exist below the columnar spacer. Therefore, since the tip of the columnar spacer is higher than the tip of the cutting portion spacer, and the adhesive is present at the difference in height, on the scribe line, the thickness of the black seal material is other than It becomes smaller than the thickness of the portion, and it is possible to perform scribing stably.

  With such a configuration, the black sealing material can be formed up to the end of the counter substrate or the TFT substrate. In this case, if the thickness of the black seal material in the scribe line is about 1 micron, the backlight can be sufficiently shielded.

  According to the present invention, when black display is performed, light leakage from the backlight from the periphery can be prevented, so that high image quality can be realized. Further, a decrease in contrast around the display area can be prevented even in normal display.

  FIG. 1 is a schematic cross-sectional view of a liquid crystal display device according to the present invention. In FIG. 1, the counter substrate 20 is bonded to the TFT substrate 10 with a black sealing material 30. The use of the black sealing material 30 in the present invention is to obtain a light shielding effect. For example, the black sealing material 30 is formed by mixing carbon, Ti black, or the like into an epoxy resin.

  In FIG. 1, light incident on the TFT substrate 10 from the light guide plate 110 reaches the end of the TFT substrate 10 while repeating total reflection. On the side surface of the TFT substrate 10, the totally reflected light travels toward the upper surface of the TFT substrate 10. At this time, conventionally, light that does not satisfy the condition of total reflection on the upper surface of the TFT substrate 10 is emitted to the counter substrate 20 and causes light leakage.

  On the other hand, in the present invention, since the black sealing material 30 is formed up to the ends of the TFT substrate 10 and the counter substrate 20, whether or not the light incident on the upper surface of the TFT substrate 10 satisfies the total reflection condition. Regardless, light is not emitted to the counter substrate 20 side. Therefore, light leakage in the peripheral area 12 of the screen can be prevented.

  Specifically, the liquid crystal display panel having such a configuration can be realized by the configuration of a mother substrate as shown in FIG. Many liquid crystal display panels are formed on a mother substrate. FIG. 2 is a cross-sectional view of the vicinity of the scribe line 15 of the liquid crystal display panel which has become the mother substrate. In FIG. 2, a black seal material 30 is formed with the scribe line 15 interposed therebetween. The black sealing material 30 in FIG. 2 is shared by adjacent liquid crystal display panels.

  The individual liquid crystal display panels are separated by stripes along the scribe lines 15 in FIG. However, the black sealing material 30 in FIG. 2 is formed to a uniform thickness. In this case, due to the influence of the black seal material 30, the stripe separation cannot be performed stably. Therefore, in the present invention, it is possible to stably scribe even if the black sealing material 30 is formed at the ends of the TFT substrate 10 and the counter substrate 20 by the method shown in the following embodiments.

  FIG. 3 is a plan view showing the first embodiment of the present invention, and is a plan view of the mother counter substrate 20 among the mother substrates. FIG. 3 is a plan view of a corner portion of four mother counter substrates 20. In FIG. 3, the dotted line is the scribe line 15. After the mother counter substrate 20 is bonded to the mother TFT substrate 10, the glass is scratched by a cutter along this line, and then the side on which the scratch is formed is applied with a bending stress to break the glass. Each liquid crystal display panel is separated from the mother substrate.

  In FIG. 3, a black matrix 50 is formed on four counter substrates 20, and columnar spacers 60 are formed on the black matrix 50. The columnar spacer 60 is used to define the distance between the counter substrate 20 and the TFT substrate 10. A cutting portion spacer 70 is formed in a portion where the scribe line 15 is formed. The cutting portion spacer 70 is formed in a linear shape having a predetermined width, and the scribe line 15 exists at the center thereof. The scribe line 15 is formed of the same material as the columnar spacer 60 in the same process. Therefore, the number of processes does not increase even if the cutting portion spacer 70 exists.

  A black sealing material 30 is formed across the scribe line 15. That is, the black sealing material 30 is continuously formed on the adjacent counter substrate 20. The black sealing material 30 is formed outside the black matrix 50 as viewed from the display area. The black sealing material 30 is desirably a thermosetting type. An overcoat film 55 (not shown) is formed on the entire FIG. Although not depicted in FIG. 3, a color filter is formed for each pixel in the display area of each counter substrate 20. Although the columnar spacer 60 is also formed in the region where the color filter is formed, it is not shown in FIG.

  4 is a cross-sectional view taken along the line AA in FIG. 3 in a state where the mother TFT substrate 10 and the mother counter substrate 20 are bonded together. In FIG. 4, a black matrix 50 is formed on each counter substrate 20 to the vicinity of the periphery. An overcoat film 55 is formed to cover the entire surface of the black matrix 50 and the counter substrate 20. The overcoat film 55 is used to prevent a color filter (not shown) from contaminating the liquid crystal layer 40.

  In the counter substrate 20, a columnar spacer 60 is formed in the display area on the overcoat film 55, and a cutting portion spacer 70 is formed in the scribe area. The columnar spacer 60 and the cut spacer 70 are formed, for example, by applying a photosensitive resin such as acrylic at a predetermined height, exposing using a mask, and developing to leave only the exposed portion. Therefore, the columnar spacer 60 and the cutting portion spacer 70 are formed simultaneously.

  As shown in FIG. 4, the columnar spacer 60 is formed on the black matrix 50 and the overcoat film 55, while the cut portion spacer 70 is formed only on the overcoat film 55. Accordingly, the height of the tip of the cut spacer 70 is formed to be lower than the height of the tip of the columnar spacer 60 by the thickness of the black matrix 50. The black matrix 50 is generally made of resin and has a thickness of about 1 μm. Therefore, a gap of about 1 micron is left between the cut portion spacer 70 and the TFT substrate 10.

  In FIG. 4, a black sealing material 30 is formed in common for adjacent liquid crystal display panels. The black sealing material 30 is also present between the cut portion spacer 70 and the TFT substrate 10, and the thickness of the black sealing material 30 is about 1 μm in this portion. After the black sealing material 30 is formed on the mother counter substrate 20, when the mother TFT substrate 10 is attached, the black sealing material 30 is crushed and spreads outward. Therefore, the distance between the cut portion spacer 70 and the TFT substrate 10 is as narrow as about 1 μm. In both cases, the black sealing material 30 can be present in the meantime. A TFT, a pixel electrode, a scanning line, a video signal line, and the like are formed on the TFT substrate 10 but are omitted in FIG. A liquid crystal is filled between the TFT substrate 10 and the counter substrate 20.

  If the black sealing material 30 is formed thick on the scribe line 15, when the glass is broken after scribing, the black sealing material 30 does not allow stable breakage. In the present invention, the scribe line 15 is formed in the portion of the cut spacer 70, and the thickness of the black seal material 30 in this portion is small. And stable scribing can be performed.

  FIG. 5 is a plan view showing a second embodiment of the present invention. In FIG. 5, a black matrix 50 is formed on four continuous opposing substrates, and columnar spacers 60 are formed on the black matrix 50. The black matrix 50 is formed of the scribe lines 15 more than in the first embodiment. It is formed close. A cutting portion spacer 70 is formed in a portion where the scribe line 15 is formed. In addition to this, in this embodiment, the seal portion weir 75 is simultaneously formed of the same material as the columnar spacer 60 and the cut portion spacer 70. Therefore, the number of processes does not increase even if the seal portion weir 75 is present. Since the seal portion weir 75 is formed on the black matrix, the height of the tip of the seal portion weir 75 is higher than the height of the tip of the cutting portion spacer 70.

  In the present embodiment, the black sealing material 30 is disposed between the two seal portion weirs 75. The black sealing material 30 is partitioned by the seal portion weir 75 and does not enter the inside of the seal portion weir 75, that is, the display region side. Therefore, since the frame area outside the display area can be accurately defined, it is not necessary to enlarge the frame area excessively in order to prevent the black sealing material 30 from protruding into the display area.

  Also in this embodiment, the black sealing material 30 is formed across the scribe line 15. That is, the black sealing material 30 is continuously formed on the adjacent counter substrate 20. In the present embodiment, the formation region of the black sealing material 30 partially overlaps with the formation region of the black matrix 50. Further, an overcoat film 55 (not shown) is formed on the entire FIG. Although not shown in FIG. 5, a color filter is formed for each pixel in the display area of each counter substrate 20, and the columnar spacer 60 is also formed in the area where the color filter is formed. Not shown.

  6 is a cross-sectional view taken along line BB in FIG. 5 in a state where the mother TFT substrate 10 and the mother counter substrate 20 are bonded together. In FIG. 6, a black matrix 50 is formed on each counter substrate 20 closer to the scribe line 15 than in the first embodiment. An overcoat film 55 is formed to cover the entire surface of the black matrix 50 and the counter substrate 20.

  In the counter substrate 20, a seal portion weir 75 is formed on the overcoat film 55 near the end of the black matrix 50, and a cut portion spacer 70 is formed in the scribe region. The seal portion weir 75 and the cutting portion spacer 70 are formed simultaneously with, for example, an acrylic resin.

  As shown in FIG. 6, the seal portion weir 75 is formed on the black matrix 50 and the overcoat film 55, while the cut portion spacer 70 is formed only on the overcoat film 55. Accordingly, the height of the cut portion spacer 70 is formed lower than the seal portion weir 75 by the thickness of the black matrix 50. Therefore, a gap of about 1 micron which is the thickness of the black matrix 50 is left between the cut portion spacer 70 and the TFT substrate 10.

  In FIG. 6, a black sealing material 30 is formed in common on adjacent liquid crystal display panels. The black sealing material 30 is also present between the cut portion spacer 70 and the TFT substrate 10, and in this portion, the thickness of the black sealing material 30 is about 1 μm, which is the same as the thickness of the black matrix 50. After the black sealing material 30 is formed on the mother counter substrate 20, when the mother TFT substrate 10 is attached, the black sealing material 30 is crushed and spreads outward, but is dammed by the seal portion weir 75 and does not enter the display area any more.

  Also in this embodiment, since the scribe line 15 is formed in the portion of the cut portion spacer 70, the thickness of the black seal material 30 in this portion is small. Therefore, the influence of the black seal material 30 is that the glass breaks after scribing. It is possible to perform stable scribing. In this embodiment, since the seal portion weir 75 is further formed, the area of the black seal material 30 is accurately partitioned, and it is not necessary to enlarge the frame area outside the display area more than necessary. Therefore, a liquid crystal display device with a small outer shape can be manufactured on the same screen.

  FIG. 7 is a plan view showing a third embodiment of the present invention. The difference between the present embodiment and the first embodiment is that, in the first embodiment, the overcoat film 55 is formed on the entire surface of the mother counter substrate 20, whereas in this embodiment, the overcoat film 55 is made of the black sealing material 30. It is that it is not formed in the formed part. In such a configuration, the black matrix 50 and the overcoat film 55 are formed on the lower side of the columnar spacer 60, whereas the cut portion spacer 70 is directly formed on the mother counter substrate 20.

  Therefore, in this embodiment, there is a total difference in the thicknesses of the black matrix 50 and the overcoat film 55 between the tip of the columnar spacer 60 and the tip of the cutting portion spacer 70. For example, when the thickness of the black matrix 50 is 1 μm and the thickness of the overcoat film 55 is 1 μm, the difference in height between the tip of the columnar spacer 60 and the tip of the cutting portion spacer 70 is about 2 μm. As described above, the present embodiment is applied to the case where the thickness of the black sealing material 30 formed between the cutting portion spacer 70 and the TFT substrate 10 is desired to be larger than that in the first embodiment or the second embodiment. I can do it.

  8 is a cross-sectional view taken along the line CC of FIG. As shown in FIG. 8, the overcoat film 55 is not present in the portion where the cut portion spacer 70 is formed. Accordingly, the distance between the cut portion spacer 70 and the TFT substrate 10 is about the same as the total thickness of the black matrix 50 and the overcoat film 55.

  Other configurations in the present embodiment are the same as those in the first embodiment, and thus description thereof is omitted. Also in the present embodiment, the scribe line 15 is formed in the portion of the cut portion spacer 70, and the thickness of the black seal material 30 in this portion is small, so the effect of the black seal material 30 is that the glass breaks after scribing. There is almost no stable scribe.

  In the first embodiment and the second embodiment, the height of the tip of the cutting portion spacer 70 and the height of the tip of the columnar spacer 60 are different depending on the thickness of the black matrix 50. In the third embodiment, the difference in height is determined by the total thickness of the black matrix 50 and the overcoat film 55. By the way, although a color filter is formed in the display area, the color filter is often formed so as to overlap with the black matrix 50. In this case, the columnar spacer 60 is formed on the black matrix 50, the color filter, and the overcoat film 55.

  When the columnar spacer 60 is formed on the color filter, the height of the tip of the cutting portion spacer 70 and the height of the columnar spacer 60 are the same as that of the black matrix 50 in the configurations corresponding to the first and second embodiments. A difference is given by the total thickness of the color filter. In this case, when the thickness of the black matrix 50 is 1 μm and the thickness of the color filter is 1 μm, the difference in height is about 2 μm.

  When the columnar spacer 60 is formed on the color filter, in the configuration corresponding to Example 3, the height of the tip of the cutting portion spacer 70 and the height of the tip of the columnar spacer 60 are equal to those of the black matrix 50, the color filter, and the like. A difference is given by the total thickness of the coating film 55. In this case, if the thickness of the black matrix 50 is 1 μm, the thickness of the color filter is 1 μm, and the thickness of the overcoat film 55 is 1 μm, the difference in height is about 3 μm.

  As described above, in the configuration of the fourth embodiment, it is desired to increase the difference between the height of the tip of the cutting portion spacer 70 and the height of the tip of the columnar spacer 60, that is, the thickness of the black seal material 30 in the scribe line 15 is implemented. It can be applied when it is desired to make it thicker than the configurations of Examples 1 to 3.

  As described above, according to the present invention, the cut portion spacer 70 made of resin is disposed in the seal portion, and the black seal material 30 is scribed by reducing the thickness of the black seal material 30 in the scribe line 15. It is possible to form up to the line 15. According to Examples 1 to 4, the thickness of the black sealing material 30 in the scribe line 15 can be set to 1 μm to 3 μm. In addition, when the thickness of the black sealing material 30 is thinner than 1 μm, the adhesive force by the black sealing material 30 may be insufficient, and when the thickness of the black sealing material 30 exceeds 3 μm, scribing may not be performed stably. There is. Therefore, the thickness of the black sealing material 30 is preferably in the range of 1 to 3 μm.
