Description

  The present invention relates to a liquid crystal display device, and more particularly to a liquid crystal display device having a color filter.

  As an image display device for personal computers and other various monitors, or a display screen of a mobile phone or a display screen of a car navigation system, there has been a remarkable spread of liquid crystal display devices. Various types of liquid crystal display devices are known, and transmissive liquid crystal display devices, reflective liquid crystal display devices, transflective liquid crystal display devices, and the like are known. Further, in a liquid crystal display device, color display using a color filter is employed. This liquid crystal display device usually has a color filter substrate including three color filters of R (Red: Red), G (Green: Green), and B (Blue: Blue) for each pixel.

  The transmissive liquid crystal display device displays an image using transmitted light from the back side. The transmissive liquid crystal display device includes a liquid crystal display panel and a backlight unit disposed on the back surface thereof. The liquid crystal display panel displays an image by controlling the transmitted light. The liquid crystal display panel can control the amount of transmitted light by enclosing a liquid crystal between two glass substrates and controlling an electric field applied to the liquid crystal. One of the two glass substrates is a color filter substrate. Liquid crystal display panels are known in modes such as TN (Twisted Nematic) and STN (Super Twisted Nematic). The backlight unit typically includes a light source and a plurality of optical members in order to effectively emit light from the light source to the liquid crystal display panel.

  As a display device having both the characteristics of a transmissive liquid crystal display device and a reflective liquid crystal display device, a transflective liquid crystal display device is known (see, for example, Patent Document 1). A transflective liquid crystal display device includes a transmissive region and a reflective region in one pixel. A reflective film provided on the pixel corresponds to the reflective region. A color filter layer other than the reflection region in the pixel corresponds to the transmission region. A color filter layer is also provided on the front side of the reflective film. The reflective film and the color filter layer are formed on the back side of the liquid crystal layer. In bright places, by using the external light reflected by the reflective film, it is possible to realize easy-to-see display and power consumption reduction. On the other hand, in a dark place, an image with excellent quality can be displayed by using light from a backlight unit that passes through the color filter layer and enters the liquid crystal layer.

  By the way, in the liquid crystal display device, it is necessary to keep the cell gap constant in order to prevent the occurrence of display unevenness. That is, if the distance between the two glass substrates is not constant, the thickness of the liquid crystal layer is partially different, and display unevenness occurs. For this reason, the spacer which regulates the space | interval is used between two glass substrates.

JP 2001-281648 A

  However, in the above-described liquid crystal display device, the cell gap may not be constant. This will be described with reference to FIG. FIG. 3 is a sectional view showing an example of the configuration of a color filter substrate of a conventional liquid crystal display device. Here, a transflective liquid crystal display device will be described as an example.

  In FIG. 3, 10 is a substrate, 21 is a reflective film, 22 is a color filter, 23 is a BM (black mask), 24 is a planarization layer, 26 is an electrode, and 27 is a step correction layer. A color filter 22 is provided on the substrate 10. The color filter 22 is patterned in a matrix, for example. Each of the color filters 22 corresponds to a pixel. As shown in FIG. 3, the entire area where the color filter 22 is provided is the display area. A desired image is displayed in the display area where the pixels are formed. For example, the color filter 22 includes three colors of R, G, and B.

  A reflective film 21 is provided on a part of the pixel. The reflective film 21 reflects light incident from the viewing side. Since the reflective film 21 is thinner than the color filter 22, the color filter 22 is also formed on the reflective film 21. Of the pixel, a portion where the reflective film is provided becomes a reflective region. on the other hand. Of the pixel, the portion where the reflective film 21 is not provided and only the color filter 22 is provided is a transmission region. A BM 23 is provided between the color filters 22. That is, a pixel is between BM23 and BM23 in the display area. BM23 is a light shielding film made of resin or chromium. The BM 23 is provided to prevent light leakage from between pixels. The BM 23 is further formed up to the end of the substrate 10. That is, the BM 23 is also formed outside the display area.

  In order to protect and planarize the color filter 22, a planarization layer 24 is formed so as to cover the color filter 22. The planarizing layer 24 is provided up to the end of the substrate 10. Therefore, the planarization layer 24 is also provided on the BM 23 outside the display area. An electrode 26 is formed on the planarization layer 24. For example, the electrode 26 is formed of a transparent conductive film. By applying a voltage to the electrode 26, the liquid crystal layer is driven. A step correction layer 27 is provided outside the display area. The step correction layer 27 will be described later.

  Although not shown in FIG. 3, spacers for holding a cell gap are scattered on the electrode 26. A sealing material is provided on the outer periphery of the substrate 10. With this sealing material, the substrate 10 and the counter substrate facing the substrate 10 are bonded together.

  Here, in the liquid crystal display device, in general, a part of the region outside the display region of the liquid crystal display panel is visually recognized from the outside. That is, a part of the area surrounding the display area on the substrate 10 is visually recognized from the outside. As shown in FIG. 3, the entire area visually recognized from the outside is set as an effective visual field area. Therefore, the effective visual field area is a slightly larger area than the display area. An area obtained by combining the display area and the frame-like area outside the display area is an effective visual field area. The area excluding the display area from the effective visual field area has a frame shape. Although this frame-shaped area is a non-display area, it is an area that is visible from the outside.

  A BM 23 is disposed outside the display area of the effective visual field area. This BM 23 can prevent light leakage. Therefore, the frame-shaped area outside the display area of the effective visual field area is visually recognized as black. Here, a step correction layer 27 for correcting a step generated by the color filter 22 is provided in a region outside the display region of the effective visual field region. That is, the color filter 22 is not provided in the frame-shaped area outside the display area in the effective visual field area. On the other hand, a color filter 22 is provided in the display area. Therefore, the surface height of the display region is higher than the surface height of the frame-like region depending on the presence or absence of the color filter 22. In order to correct a step caused by the difference in surface height, a step correction layer 27 is provided in the frame-like region in the effective visual field region. This step correction layer 27 can reduce changes in the cell gap in the vicinity of the display area. That is, by providing the step correction layer 27, display unevenness in the vicinity of the display area can be reduced.

  However, the surface height outside the step correction layer 27, that is, outside the effective visual field region is lower than the effective visual field region. That is, a step a occurs between the outside and inside of the effective visual field area. When such a level difference occurs, the spacer that keeps the cell gap constant outside the effective visual field region and the two substrates are not in contact with each other. That is, an interval is generated between the spacer and one substrate. Therefore, it becomes impossible to regulate the substrate interval outside the effective visual field region. Accordingly, when a force is applied to the liquid crystal display panel, the liquid crystal display panel is warped. Due to this warpage, the cell gap is not constant and display unevenness occurs. This display unevenness occurs not only in the transflective liquid crystal display device but also in the transmissive and reflective liquid crystal display devices. That is, in the case of a liquid crystal display device using a color filter, the above display unevenness may occur.

As described above, the conventional liquid crystal display device has a problem that display unevenness occurs.
The present invention has been made in view of such problems, and an object thereof is to provide a liquid crystal display device capable of reducing display unevenness.

  A liquid crystal display device according to a first aspect of the present invention is a liquid crystal display device having a liquid crystal layer sandwiched between a first substrate and a second substrate, wherein pixels in a display region are formed on the first substrate. Corresponding color filters and a step correction layer disposed outside the color filter and provided in an effective visual field area visually recognized from the outside are formed on the first substrate and the second substrate. A sealing material that seals the sandwiched liquid crystal layer, a first spacer that is provided in the display region and regulates a distance between the first substrate and the second substrate, the step correction layer, and the seal And a second spacer having a diameter larger than that of the first spacer. Thereby, generation | occurrence | production of the display nonuniformity can be reduced.

  In the liquid crystal display device according to the second aspect of the present invention, in the above-described liquid crystal display device, a reflective film is formed on at least a part of the pixels, and the reflective film and the step correction layer are formed of the same material. It is what. Thereby, a manufacturing process can be simplified.

  The liquid crystal display device according to a third aspect of the present invention is the above-described liquid crystal display device, wherein the diameter of the second spacer is larger than the diameter of the first spacer by the thickness of the step correction layer. is there. Thereby, the occurrence of display unevenness can be effectively reduced.

  The liquid crystal display device according to a fourth aspect of the present invention is the above-described liquid crystal display device, wherein the diameter of the second spacer is higher than the diameter of the first spacer and the surface height outside the effective visual field region and the surface height. The difference is the difference from the surface height of the display area. Thereby, the occurrence of display unevenness can be effectively reduced.

  ADVANTAGE OF THE INVENTION According to this invention, the liquid crystal display device which can reduce display nonuniformity can be provided.

  Hereinafter, embodiments to which the present invention can be applied will be described. The following description explains the embodiment of the present invention, and the present invention is not limited to the following embodiment.

  A configuration of a liquid crystal display panel used in the liquid crystal display device according to the present invention will be described with reference to FIG. FIG. 1 is a cross-sectional view showing a configuration of a liquid crystal display panel of a liquid crystal display device according to the present invention. Here, a semi-reflective / semi-transmissive liquid crystal display device will be described as an example.

  In FIG. 1, 10 is a substrate, 20 is a counter substrate, 21 is a reflection film, 22 is a color filter, 23 is a BM (black mask), 24 is a planarization layer, 26 is an electrode, 27 is a step correction layer, and 31 is a first correction layer. , 32 is a second spacer, and 33 is a sealing material.

  The substrate 10 and the counter substrate 20 are, for example, transparent glass substrates. The substrate 10 and the counter substrate 20 are disposed to face each other. A liquid crystal layer (not shown) is sandwiched between the substrate 10 and the counter substrate 20. The liquid crystal display panel can use a mode such as TN (Twisted Nematic) or STN (Super Twisted Nematic). A backlight unit (not shown), which is a planar light source device, is provided on the back side of the substrate 10. The light from the backlight unit passes through the liquid crystal layer and is emitted to the counter substrate 20 side. The backlight unit typically includes a light source and a plurality of optical members for effectively emitting light from the light source to the liquid crystal display panel.

  A color filter 22 is provided on the substrate 10. That is, the substrate 10 is a color filter substrate on which the color filter 22 is formed. The color filter 22 is patterned in a matrix. Each of the color filters 22 corresponds to a pixel. As shown in FIG. 1, the entire area where the color filter 22 is provided is the display area. A desired image is displayed in the display area where the pixels are formed. The color filter 22 includes, for example, three colors of R (Red), G (Green), and B (Blue).

  A BM 23 is provided between the color filters 22. That is, a pixel is between BM23 and BM23 in the display area. BM23 is a light shielding film made of resin or chromium. The BM 23 is provided to prevent light leakage from between pixels. The BM 23 is further formed up to the end of the substrate 10. That is, the BM 23 is also formed outside the display area in order to prevent light leakage around the display area.

  A reflective film 21 is provided on a part of the pixel. The reflective film 21 reflects light incident from the viewing side. Since the reflective film 21 is thinner than the color filter 22, the color filter 22 is also formed on the reflective film 21. Of the pixel, a portion where the reflective film is provided becomes a reflective region. In the reflection area, light incident from the outside is reflected. on the other hand. Of the pixel, the portion where the reflective film 21 is not provided and only the color filter 22 is provided is a transmission region. In the transmissive region, light from the backlight unit is transmitted. With such a configuration, a pixel of a transflective liquid crystal display device is formed. The reflective film 21 can be formed of, for example, a metal thin film having a thickness of 0.1 to 0.3 μm.

  In order to protect and planarize the color filter 22, a planarization layer 24 is formed so as to cover the color filter 22. The planarizing layer 24 is provided up to the end of the substrate 10. Therefore, the planarization layer 24 is also provided on the BM 23 outside the display area.

  An electrode 26 is formed on the planarization layer 24. For example, the electrode 26 is formed of a transparent conductive film. By applying a voltage to the electrode 26, the liquid crystal layer is driven. For example, in a passive matrix liquid crystal display device, the electrodes 26 are formed in a stripe shape. The counter substrate 20 is provided with electrodes (not shown) orthogonal to the electrode 26. The electrode of the counter substrate 20 is also formed of a transparent conductive film. One of the electrodes of the substrate 10 and the counter substrate 20 is a signal electrode, and the other is a scanning electrode. A voltage is applied between the electrode 26 of the substrate 10 and the electrode of the counter substrate 20. As a result, an electric field applied to the liquid crystal is generated. By controlling this electric field, the amount of light transmitted through the liquid crystal display panel can be controlled. Of course, the present invention is not limited to the passive matrix type liquid crystal display device, and can be used for an active matrix type or segment type liquid crystal display device. Note that an alignment film that aligns liquid crystal in a predetermined direction may be formed on the electrode 26 and the electrode of the counter substrate 20.

  A sealing material 33 is provided at the end of the substrate 10. The sealing material 33 is provided in a frame shape so as to surround the entire end portion of the substrate 10. The substrate 10 and the counter substrate 20 are bonded together by the sealing material 33. The sealing material 33 seals the liquid crystal layer sandwiched between the substrate 10 and the counter substrate 20. In FIG. 1, the sealing material 33 is formed on the planarizing layer 24, but may be formed directly on the substrate 10.

  A step correction layer 27 is provided outside the display area. The step correction layer 27 will be described later.

  Here, in the liquid crystal display device, generally, an area outside the display area is visually recognized from the outside. That is, a part of the area surrounding the display area on the substrate 10 is visually recognized from the outside. As shown in FIG. 1, the entire area visually recognized from the outside is set as an effective visual field area. Therefore, the effective visual field area is a slightly larger area than the display area. That is, the effective visual field region is a region obtained by combining the display region and the frame-like region outside the display region. The area excluding the display area from the effective visual field area has a frame shape. Although this frame-shaped area is a non-display area, it is an area that is visible from the outside.

  A BM 23 is disposed outside the display area of the effective visual field area. This BM 23 can prevent light leakage. Therefore, the frame-shaped area outside the display area of the effective visual field area is visually recognized as black. Here, a step correction layer 27 for correcting a step generated by the color filter 22 is provided in a region outside the display region of the effective visual field region. That is, the color filter 22 is not provided in the frame area of the effective visual field area. On the other hand, a color filter 22 is provided in the display area. Therefore, the surface height of the display region is higher than the surface height of the frame-like region depending on the presence or absence of the color filter 22. In order to correct a step caused by the difference in surface height, a step correction layer 27 is provided in the frame-like region in the effective visual field region. The step correction layer 27 is patterned in a frame shape so as to surround the display area. The step correction layer 27 can be formed by the same process as the reflective film 21. In this case, the step correction layer 27 is formed of the same material as the reflective film 21. Thereby, a manufacturing process can be simplified and productivity can be improved. In this case, the step correction layer 27 is formed with a film thickness of 0.1 to 0.3 μm, which is the same as the reflective film 21. This step correction layer 27 can reduce changes in the cell gap in the vicinity of the display area. That is, by providing the step correction layer 27, display unevenness in the vicinity of the display area can be reduced.

  Here, steps due to the presence or absence of the step correction layer 27 occur between the inside and outside of the effective visual field region. In the present invention, the first spacer 31 and the second spacer 32 having different heights are provided in order to reduce display unevenness due to the step. The first spacer 31 and the second spacer 32 are spherical spacers. The first spacer 31 is disposed in the effective visual field area, and the second spacer 32 is disposed outside the effective visual field area. Here, in order to reduce the change in the cell gap caused by the presence or absence of the step correction layer 27, the diameter of the first spacer is smaller than the diameter of the second spacer. That is, there is a difference in the surface height of the substrate 10 between the inside and outside of the effective visual field region depending on the presence or absence of the step correction layer 27. The difference in diameter between the second spacer 32 and the first spacer 31 corresponds to the difference in the surface height of the substrate 10 inside and outside the effective visual field region. Therefore, the difference in diameter between the second spacer 32 and the first spacer corresponds to the difference between the surface height outside the effective visual field region and the surface height of the display region. In addition, the surface height of the outside of the effective visual field area and the display area is an average value of the surface height in each area. For example, the difference in diameter between the second spacer 32 and the first spacer 1 can be matched with the film thickness of the step correction layer 27. The second spacer 32 is made larger than the first spacer 31 by this difference. Thereby, the second spacer 32 is in contact with the surfaces of the substrate 10 and the counter substrate 20 even outside the effective visual field region. Further, the first spacer 31 is in contact with the surfaces of the substrate 10 and the counter substrate 20 even in the effective visual field region. Therefore, the spacers are in contact with the surfaces of the substrate 10 and the counter substrate 20 over the entire surface of the liquid crystal display panel 1. Therefore, the substrate interval can be regulated not only inside but also outside the effective visual field region. Thereby, the curvature of the liquid crystal display panel 1 can be prevented, and display unevenness can be reduced.

  Next, the manufacturing process of the liquid crystal display panel 1 will be described. First, the reflective film 21 and the step correction layer 27 are formed on the substrate 10. Specifically, a metal thin film such as Al is formed by vapor deposition or sputtering. Then, the metal thin film is patterned by photolithography to form the reflective film and the step correction layer 27. The reflective film 21 and the step correction layer 27 can be formed with a thickness of 0.2 μm, for example.

  Next, the BM 23 is formed on the step correction layer 27. The BM 23 is formed of, for example, a resin in which metallic chromium, carbon, or titanium is dispersed in a photoresist. When metallic chromium is used, the BM 23 is patterned by photolithography as shown in FIG. When the resin BM is used, the BM 23 is patterned as shown in FIG. 1 by performing application, exposure and development.

  Subsequently, the color filter 22 is formed by applying, exposing and developing a photosensitive coloring material by a pigment dispersion method or the like. For each of the R, G, and B photosensitive coloring materials, coating, exposure, and development are repeated to form a three-color color filter 22. Here, first, a colored layer having the same thickness as that of the reflective film 21 and the step correction layer 27, that is, a 0.2 μm colored layer is formed. Thereby, a color filter is formed in a region where the reflective film 21 of the pixel is not formed. Then, a colored layer having a thickness of 0.8 μm is provided on the reflective film 21 and the color filter having the same thickness as the reflective film by the same method. Thereby, the color filter 22 having the shape shown in FIG. 1 can be formed.

  Thereafter, a planarizing layer 24 is formed on the BM 23 and the color filter 22. The planarization layer 24 can be formed of a resin.

  An electrode 26 is formed on the planarizing layer 24. First, a transparent conductive film such as ITO is formed by sputtering or vapor deposition. Then, the transparent conductive film is patterned by photolithography. Thereby, the electrode 26 as shown in FIG. 1 is formed. Note that an alignment film may be provided over the electrode 26 to perform rubbing treatment.

  An electrode is also formed on the counter substrate 20 by the same process as described above. Further, an alignment film may be provided on the electrode of the counter substrate 20. In the TN mode and the STN mode, rubbing is performed so that the alignment directions of the alignment films of the substrate 10 and the counter substrate 20 are orthogonal to each other.

  Then, a sealing material 33 is applied on the substrate 10. The sealing material 33 can be applied using a dispenser. Or you may form the sealing material 33 using screen printing. Here, the sealing material 33 is arranged in a frame shape except for the liquid crystal injection port. For the sealing material 33, a thermosetting resin or a photocurable resin is used. For example, an epoxy resin can be used as the sealing material 33. The sealing material 33 is disposed outside the frame-shaped step correction layer 27. That is, the region where the step correction layer 27 is provided and the region where the sealing material 33 is formed are separated from each other. As a result, the frame-shaped step correction layer 27 is not disposed below the sealing material 33. Therefore, peeling of the sealing material 33 can be prevented. That is, since the step correction layer 27 is formed in a frame shape, if the step correction layer 27 is under the sealing material 33, the step correction layer 27 is formed under the entire sealing material 33. In this case, peeling of the sealing material 33 is likely to occur. Therefore, it is preferable to form the sealing material 33 outside the frame-shaped step correction layer 27.

  The first spacer 31 and the second spacer 32 are sprayed from the top of the substrate 10 on which the sealing material 33 is formed. The spacer spreading process will be described with reference to FIG. FIG. 2 is a diagram for explaining the spacer spraying process, and schematically shows the substrate 10 as viewed from above. Here, when the first spacer 31 and the second spacer 32 are sprayed from above using the spray nozzle of the spacer spraying device, a mask corresponding to each spray region is used. Specifically, when the first spacers 31 are dispersed, a mask in which the first mask region 35 shown in FIG. 2A is formed is disposed on the substrate. The first mask area 35 coincides with an area outside the effective visual field area. That is, the area not masked by the first mask area 35 coincides with the effective visual field area. Thereby, the area | region outside an effective visual field area | region is masked, and the 1st spacer 31 can be spread | dispersed only in an effective visual field area | region.

  On the other hand, when the second spacer 32 is sprayed, a mask in which the second mask region 36 shown in FIG. 2B is formed is disposed on the substrate. The second mask area 36 coincides with the effective visual field area. Thereby, the effective visual field region is masked, and the second spacers 32 can be scattered only in the region outside the effective visual field region. Therefore, as shown in FIG. 2C, the first spacers 31 and the second spacers 32 can be dispersed in a predetermined region. Thus, in this invention, the diameter of a spacer is changed according to a level | step difference. The particle diameter of the spacer can be changed in increments of 0.05 μm, for example. Accordingly, display unevenness can be easily reduced.

  Note that the order in which the first spacers 31 and the second spacers 32 are dispersed is not particularly limited. That is, after the first spacer 31 is sprayed, the second spacer 32 may be sprayed. Alternatively, the first spacers 31 may be sprayed after the second spacers 32 are sprayed. Further, when the first spacers 31 are dispersed, a mask may not be used. In this case, the first spacers 31 are scattered over the entire surface of the substrate 10. That is, the first spacers 31 are scattered outside the effective visual field region. However, since the first spacer 31 is smaller than the second spacer 32, the change in the cell gap is not affected. Thereafter, in the above description, the spacers are dispersed on the substrate 10, but the spacers may be dispersed on the counter substrate 20. In this case, after forming a sealing material on the counter substrate 20, spacers are dispersed by the same method as described above.

  Then, the board | substrate 10 and the opposing board | substrate 20 are made to oppose, and the sealing material 33 is hardened. Thereby, the board | substrate 10 and the opposing board | substrate 20 are bonded together. At this time, the sealing material is cured while pressing the counter substrate 20. The first spacer 31 and the second spacer 32 between the substrate 10 and the counter substrate 20 are slightly crushed and deformed. The first spacer 31 and the second spacer 32 are in contact with the surfaces of the substrate 10 and the counter substrate 20. Therefore, the substrate interval is regulated by the first spacer 31 and the second spacer 32. Then, liquid crystal is injected from an injection port provided in the sealing material 33. A liquid crystal display panel is completed by sealing the inlet. By using such a manufacturing method, a liquid crystal display device with reduced display unevenness can be manufactured by a simple method.

  In the above description, the transflective liquid crystal display device has been described. However, the present invention can be used for reflective and transmissive liquid crystal display devices. That is, it can be used for a display device having a color filter. In transflective and reflective liquid crystal display devices, a reflective film can be used as a step correction layer. Thereby, a manufacturing process can be simplified. A color filter can also be used as the step correction layer 27. In the above description, two types of spherical spacers having different diameters are used, but three or more types of spherical spacers having different diameters may be used depending on the level difference.

It is a figure which shows typically the area | region where a spacer is spread | dispersed in the liquid crystal display device concerning this invention.
