Description

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

  The liquid crystal display device is configured to control the light transmittance of the liquid crystal in each of a plurality of pixels constituting the display unit.

  That is, in a liquid crystal display device, a pair of substrates sandwiching a liquid crystal is configured as an envelope, and each pixel is formed on the liquid crystal side surface of one of these substrates (hereinafter sometimes referred to as a first substrate). An electronic circuit for generating an electric field in the liquid crystal is formed.

  Further, in order to display an image obtained by light transmitted through each pixel in color, a color filter is required, and this color filter may be referred to as, for example, the other substrate (hereinafter referred to as a second substrate) among the substrates. It is formed on the liquid crystal side surface.

  In this case, a light shielding film called a black matrix is usually formed between adjacent pixels on the liquid crystal side surface of the second substrate, and a color filter is formed so as to cover the region of the pixels. The black matrix is provided to improve display contrast.

  The color filter is made of, for example, red, green, and blue, and these color filters are assigned to three pixels adjacent to each other to constitute a unit pixel for color display.

  Note that with the recent increase in size, a plurality of liquid crystal display devices are formed so as to interpose so-called columnar spacers between the first substrate and the second substrate at least in the region constituting the display portion. The gap of the second substrate is secured to make the layer thickness of the liquid crystal uniform.

  As a document related to the present invention, for example, there is the following Patent Document 1. In Patent Document 1, a color filter is formed on the upper surface of a black matrix, and a spacer (referred to as a photo spacer) is formed on the upper surface of the color filter, and the color filter has two colors having different colors in a portion overlapping with the spacer. A configuration in which filters are formed in an overlapping manner is disclosed. Accordingly, there is a description that a spacer having a low height can be used.

JP 2003-107493 A

  Here, an example of a specific configuration of the black matrix, the color filter, and the columnar spacer formed on the second substrate as described above is as shown in FIG. 10 is a plan view of the substrate (second substrate) SUB2 as viewed from the liquid crystal side, FIG. 11 is a sectional view taken along line XI-XI in FIG. 10, and FIG. 12 is a sectional view taken along line XII-XII in FIG. FIG. 10 is a diagram drawn in correspondence with FIG. 1 showing an embodiment of the present invention. For this reason, in FIG. 10, description of the configuration other than the main part is omitted, but for the configuration, refer to the description of the embodiment.

  First, in FIG. 10, a black matrix BM is formed on the liquid crystal side surface of the substrate SUB2. The black matrix BM is formed between the pixels PIX adjacent in the y direction in the drawing and between the pixels PIX adjacent in the x direction in the drawing. As a result, the black matrix BM is formed as a grid pattern in which openings are provided in each pixel PIX.

  A color filter CF is formed covering the black matrix BM. The color physical CF forms a color common to the respective pixels PIX arranged in parallel in the y direction in the drawing, and a red (R) color physical CF (indicated by a symbol CFr in the drawing) along the x direction in the drawing. A green (G) color filter CF (indicated by the symbol CFg in the figure) and a blue (B) color filter CF (indicated by the symbol CFb in the figure) are sequentially and repeatedly formed.

Here, in FIG. 10, the color filter CF shows only the color physical CFb, and the color filters CFr and CFg of other colors are omitted. The color filters CFr and CFg have the same pattern as that of the color physical CFb, so that the drawing is not complicated by the illustration. However, in FIGS. 11 and 12, the cross section is drawn assuming that all of the color physicals CFr, CFg, and CFb exist in FIG.

  A flattening film OC is formed covering the thus-formed color physicals CFr, CFg, and CFb, and a portion of the upper surface of the flattening film OC that extends in the x direction of the black matrix BM. A columnar spacer SOC is formed so as to overlap with a part of the spacer.

  In this case, as shown in FIG. 12, the region where the black matrix BM is formed and the region of the pixel PIX where the black matrix BM is not formed have a level difference corresponding to the thickness of the black matrix BM. Usually, the surface of the planarizing film OC made of a resin film formed by coating is formed so that almost no step is generated. However, when configured in this way, a sealing material (indicated by reference numeral SL in FIG. 2) that seals the liquid crystal between the first substrate and the second substrate and also serves to fix the first substrate to the second substrate is used. It has been found that inconvenience occurs when the two substrate surfaces are formed by printing using a squeegee.

  FIG. 13 is a diagram schematically showing a case where the sealing material is formed by printing. In FIG. 13, when the sealing material SL is printed in a predetermined pattern on the surface of the substrate SUB, the printing plate PRB is disposed so as to face the substrate SUB2. In this printing plate PRB, a mesh portion MS is formed at a portion corresponding to the pattern. Then, the seal material SL ′ applied on the printing plate PRB is pushed out from the mesh part MS to the substrate SUB2 side by the operation of the squeegee SK.

  In the liquid crystal display device, when the sealing material SL is formed on the second substrate on which the color filter CF or the like is formed, an alignment film (not shown) in which the surface of the planarization film OC shown in FIGS. )) Is formed. In this case, as shown in FIG. 14 which is a cross-sectional view taken along the line XIV-XIV in FIG. 10, it is not a problem that the printing plate PRB abuts on the surface (non-display area) on the black matrix BM. It will also contact the alignment film (not shown) in this region. This causes a so-called mesh mark on the rubbing surface of the alignment film.

  FIG. 15 is a configuration diagram in which such an inconvenience is solved, and is a diagram drawn corresponding to FIG. 15 is a plan view of the substrate (second substrate) SUB2 as viewed from the liquid crystal side, FIG. 16 is a sectional view taken along line XVI-XVI in FIG. 15, and FIG. 17 is a sectional view taken along line XVII-XVII in FIG.

  In FIG. 15, a configuration different from that in FIG. 10 is, for example, a blue (B) color filter CFb. In other words, the color physical CFb is a pattern that is connected to another color filter CFb of the same color arranged adjacent to each other by an extended portion CFSb that extends over the black matrix BM that extends in the x direction in the drawing. It is in the point formed by. The color filters CFr and CFg are omitted in the same manner as in FIG. 5, but have the same pattern as described in FIG.

  By doing so, as shown in FIG. 18 which is a cross-sectional view taken along line XVIII-XVIII in FIG. 15, even if the printing plate PRB contacts the surface (non-display area) on the black matrix BM, A sufficient gap G can be ensured between the pixel PIX and an alignment film (not shown) in the region of the pixel PIX, and the anxiety of being in contact with the alignment film can be eliminated.

  However, in the case of such a configuration, on the black matrix BM extending in the x direction shown in FIG. 15, as is apparent from FIG. 16, the color filter CFb is formed in only one layer in the formation region. However, in the formation region of the color filter CFr and the color filter CFg, the extension portion CFSb of the color filter CFb is formed so as to overlap. For this reason, for example, on the surface of the planarizing film OC, the concave portion DNT is formed in the formation region of the color filter CFb, and the inclined surface SLP is formed between the surfaces in the formation regions of the color filter CFr and the color filter CFg. It will be.

  This is because, for example, when the columnar spacer SOC is arranged in the vicinity of the position shown in the drawing, it is limited to the flat bottom surface of the concave portion DNT, and there is a disadvantage that it cannot be arranged on the inclined surface SLP. Become. The vicinity of the columnar spacer SOC shown in the figure is a region where a thin film transistor, a contact hole, or the like is formed. The columnar spacer SOC is placed at a location where the inclined surface SLP is formed avoiding these locations. It may be preferable to arrange.

  An object of the present invention is to provide a liquid crystal display device in which a black matrix (light-shielding film) and a color filter are overlapped, and a restriction can be eliminated at a position where a columnar spacer is disposed.

  In the liquid crystal display device of the present invention, a color filter of one color is not formed on the upper surface of a portion extending in one direction of the black matrix (light-shielding film), and two color filters of different colors are superimposed. It is comprised so that it may be formed.

  FIG. 2 is a schematic plan view showing Example 1 of the liquid crystal display device to which the present invention is applied.

  In FIG. 2, there are a first substrate SUB1 and a second substrate SUB2 which are arranged to face each other with a liquid crystal (not shown) interposed therebetween. The first substrate SUB1 has a larger area than the second substrate SUB2, and has, for example, a portion exposed from the second substrate SUB2 on the lower side in the drawing. In this portion, a semiconductor device (chip) SEC for driving the pixels of the liquid crystal display device is mounted. The second substrate SUB2 is fixed to the first substrate SUB1 by a sealing material SL formed around the second substrate SUB2, and the sealing material SL also has a function of sealing the liquid crystal between the first substrate SUB1 and the second substrate SUB2. It has become.

  An area surrounded by the sealing material SL constitutes a display area (display unit) AR, and a large number of pixels PIX arranged in a matrix are formed in the display area AR. These pixels PIX are configured as follows, for example. First, on the liquid crystal side surface of the first substrate SUB1, a plurality of gate signal lines GL extending in the x direction in the drawing and arranged in parallel in the y direction, and extending in the y direction in the drawing and arranged in parallel in the x direction. A plurality of drain signal lines DL are formed. Each pixel PIX is formed in a region surrounded by a pair of adjacent gate signal lines GL and a pair of adjacent drain signal lines DL. As shown in the enlarged view of A in FIG. A thin film transistor TFT that is turned on by a scanning signal, a pixel electrode PX that is supplied with a video signal from the drain signal line DL through the turned on thin film transistor TFT, and a counter electrode CT that generates an electric field between the pixel electrode PX It comprises. The counter electrode CT is supplied with a reference signal serving as a reference for the video signal through, for example, a common signal line CL extending in the x direction and juxtaposed in the y direction. The scanning signal in the gate signal line GL, the video signal in the drain signal line DL, and the reference signal in the common signal line CL are supplied from the semiconductor device SEC.

  In FIG. 2, the pixel structure is shown by an equivalent circuit. Specifically, patterned conductive films, insulating films, semiconductor films, and the like are stacked in a predetermined order by selective etching using a photolithography technique. The circuit is formed.

  The liquid crystal display device shown in FIG. 2 is of a so-called lateral electric field type such as IPS (In Plane Switching) that drives the liquid crystal by generating an electric field having a component parallel to the surface of the first substrate SUB2. Is. However, the present invention is not limited to this, and can also be applied to a vertical electric field system such as TN (Twisted Nematic) or VA (Vertical Alignment).

  FIG. 3 is a plan view in which the second substrate SUB2 is removed from the liquid crystal display device shown in FIG. 2, and the second substrate SUB2 is viewed from the surface on the liquid crystal side.

  A black matrix BM is first formed on the liquid crystal side surface of the second substrate SUB2. The black matrix BM is formed as a grid pattern in which an opening (dotted line frame in the figure) is provided in each pixel PIX in the display area (display unit) AR surrounded by the sealing material SL. The black matrix BM is formed so as to cover at least the gate signal line GL, the drain signal line DL, and the thin film transistor TFT shown in FIG.

  A color filter CF is formed on the surface on which the black matrix BM is formed. The color filter CF is composed of, for example, red (R), green (G), and blue (B). In FIG. 3, color filters of the same color are formed in common in the pixels PIX arranged in parallel in the y direction in the drawing, and color filters of other different colors are arranged along the x direction in the drawing. It is arranged repeatedly. In FIG. 3, for example, from the right side of the figure, the red (R) color filter CF (indicated by the symbol CFr), the green (G) color filter CF (indicated by the symbol CFg), and the blue (B) The color filters CF (indicated by the symbol CFb in the figure) are repeatedly arranged in this order. A unit pixel for color display is composed of three pixels arranged adjacent to each other in the x direction in the figure.

  Hereinafter, the color filter CFr, the color filter g, and the color filter CFb will be described in detail. FIG. 1 is an enlarged plan view showing a 2 × 4 pixel portion of each pixel shown in FIG. 4 is a cross-sectional view taken along line IV-IV in FIG. 1, and FIG. 5 is a cross-sectional view taken along line V-V in FIG.

  First, the black matrix BM is formed on the liquid crystal side surface of the substrate SUB2. The black matrix BM is formed between the pixels PIX adjacent in the y direction in the drawing and between the pixels PIX adjacent in the x direction in the drawing. As a result, the black matrix BM is formed as a grid pattern in which openings are provided in each pixel PIX.

  A color filter CFr is first formed on the upper surface of the black matrix BM. The color filter CFr is not shown in FIG. 1 to avoid complication (however, it is shown in FIGS. 4 and 5), but covers the pixel PIX denoted by reference numeral R in FIG. It is formed as a strip pattern extending in the y direction in the figure. For this reason, the end of the color filter CFr in the longitudinal direction is positioned on the drain signal line DL, and a part thereof is formed without having a portion extending in the x direction in the drawing.

  The color filter CFg is formed so as to extend in the y direction in the figure so as to cover the pixel PIX denoted by reference numeral G in FIG. In this case, the color filter CFg extends in the x direction in the drawing on the side opposite to the side on which the color filter CFr is formed, as shown in FIG. 6 in which only the black matrix BM and the color filter CFg are drawn. The extending portion CFSg extends on the black matrix BM, and the extending portion CFSg is formed in a range overlapping with a portion where a color filter CFb described later is formed (excluding an extending portion CFSb described later).

  The color filter CFb is formed so as to extend in the y direction in the figure so as to cover the pixel PIX denoted by reference numeral B in FIG. In this case, as shown in FIG. 7 in which only the black matrix BM and the color filter CFg are extracted and drawn, the color filter CGb is adjacent to the other blue (B) color filter CFb arranged in the x direction in the drawing. Are formed in a pattern connected by an extended portion CFSb extending on the black matrix BM.

  A flattening film OC is formed covering the color filters CFr, CFg, and CFb formed in this way, and the upper surface of the flattening film OC and the portion of the black matrix BM that extends in the x direction in the figure. A columnar spacer SOC is formed so as to overlap a part. This columnar spacer SOC can be formed by forming a resin film, for example, by selective etching using a photolithography technique, and can be formed at a desired location at a desired height.

  When configured in this manner, the color filter CF laminated on the black matrix BM extending in the x direction in FIG. 1 has two layers (strictly speaking) in the portion along the extending direction of the black matrix BM. There is a portion with three layers, but the width of this portion is small and can be ignored), and there is no portion that becomes one layer. Therefore, the surface of the planarizing film OC formed by covering the color filter CF can be sufficiently planarized. Therefore, when the columnar spacer SOC is formed so as to overlap with a part of the black matrix BM that extends in the x direction in FIG. 1, the arrangement of the columnar spacer SOC is not restricted.

  Further, as is apparent from FIG. 5, since the lamination of the two color filters CF can be secured on the black matrix BM in the portion extending in the x direction in FIG. When the sealing material SL is formed by printing, the disadvantage that a so-called mesh mark is generated on the rubbing surface of the alignment film can be solved.

  In the first embodiment, the color filter CF is formed by stacking the red (R) color filter CFr, the green (G) color filter CFg, and the blue (B) color filter CFb in this order. is there.

  However, as shown in FIG. 8 drawn corresponding to FIG. 4, the red (R) color filter CFr, the blue (B) color filter CFb, and the green (G) color filter CFg are stacked in this order. It may be configured. In this case, the planar patterns of the color filters CFr, CFb, and CFg are the same as the planar patterns of the corresponding color filters CFr, CFb, and CFg shown in the first embodiment.

  Even in this case, the color filter CF laminated on the black matrix BM is formed in two layers in the portion along the extending direction of the black matrix BM, and has the same effect as that of the first embodiment. An effect comes to be acquired.

  Also in Example 3, as shown in FIG. 9, the case where the laminated structure of each color filter CFr, CFb, CFg is different is shown.

  FIG. 9 is also a diagram drawn corresponding to FIG. 4, in which the blue (B) color filter CFb, the red (R) color filter CFr, and the green (G) color filter CFg are stacked in this order. You may make it. Also in this case, the plane patterns of the color filters CFb, CFr, and CFg are the same as the plane patterns of the corresponding color filters CFb, CFr, and CFg shown in the first embodiment.

  Even in this case, the color filter CF laminated on the black matrix BM is formed in two layers in the portion along the extending direction of the black matrix BM, and has the same effect as that of the first embodiment. An effect comes to be acquired.

  In each of the above-described embodiments, the columnar spacer SOC is formed on the second substrate SUB2 side. However, the present invention is not limited to this, and it may be formed on the first substrate SUB1 side.

  When the columnar spacer SOC can be formed on the surface of the first substrate SUB1 on the surface with less unevenness, at least the surface that contacts the head of the columnar spacer SOC is flat on the liquid crystal side surface of the first substrate SUB2. This is because it is preferable.

  The black matrix BM shown in FIG. 1 has a pattern formed between the pixels PIX adjacent in the y direction in FIG. 1 and between the pixels PIX adjacent in the x direction in the drawing. However, it may be configured by a pattern in which a portion formed between each pixel PIX adjacent in the x direction in the figure is eliminated. That is, it may be a black matrix BM having a pattern covering the gate signal line GL.

  The present invention has been described using the embodiments. However, the configurations described in the embodiments so far are only examples, and the present invention can be appropriately changed without departing from the technical idea. Further, the configurations described in the respective embodiments may be used in combination as long as they do not contradict each other.
