Field of the Invention The present invention relates to a liquid crystal display device, and more particularly to a liquid crystal display device which suppresses chromaticity change of a viewing angle and improves contrast, and a method of manufacturing the same. [Prior Art] In the liquid crystal display device, the contrast Δη.d ' between the refractive index anisotropy Δη of the liquid crystal and the layer thickness (cell gap) d of the liquid crystal layer changes its contrast and the viewing angle. When displayed in the normal black mode, the contrast in the front direction is lowered. Further, in a liquid crystal display device in which a multi-color display is not used in a multi-color color filter represented by three colors of red, green, and blue, the frequency of display light passing through the color filter through the liquid crystal is different. Therefore, Δη (1 also changes and chromaticity changes) when the viewing angle is changed. Fig. 1 is an explanatory view showing a configuration example of the 丨 pixel of the liquid crystal display device, Fig. 12(a) shows a plane, and Fig. 12(b) shows Fig. 12 (Fig. 12( a) A-A1 line cross section. The liquid crystal display device is a so-called TNs, and an inner surface of an insulating substrate (hereinafter referred to as a glass substrate) SUB1 has a thin film transistor (TFT) and a pixel electrode driven by the TFT. Each of the pixel electrodes ρ χ constitutes a sub-pixel (Subpixel) for color display, which is simple and simple, and is referred to as a pixel unless otherwise necessary. In FIG. 12, a diagram of a glass substrate provided on the other side of the counter electrode is omitted. Further, the liquid crystal display device is configured by combining a drive circuit, a display control circuit substrate, a backlight, and other constituent members on the liquid crystal display panel. The present invention is based on the configuration of the liquid crystal display panel, so the liquid crystal display panel is used. The liquid crystal display device is also referred to as a TFT substrate or an active matrix substrate, and has: 129638.doc 200907489 a closed electrode GT which is composed of an interpolar line GLf; and a closed insulating layer ι a semiconductor layer AS' The stone layer is better than the conductor layer (ohmic contact layer); the source electrode (or the drain electrode) and the drain electrode (or the source electrode) sd; the protective layer (purification layer) PAS, and the pixel electrode The pixel electrode (10) is electrically connected to the source electrode (or the drain electrode) by a via hole opened to the protective layer PAS. In addition, the drain electrode SD (or source electrode) is from the data line (bungee line) team. The extension is formed on the η + semiconductor layer. In this configuration example, the pixel region is transversely arranged, and a capacitor line ce is disposed under the pixel electrode. FIG. 13 is a view showing light of each color of the liquid crystal display device shown in FIG. Schematic diagram of transmittance. The same symbol as in Fig. 12 corresponds to the same functional part. SUB2 is the other glass substrate described above, and is provided with color filters C'-R (red) and CF-G (green). , CF_B (blue)', so the substrate is called color 遽The photoreceptor substrate (CF substrate), the color filters CF_R, CF_G, and π" respectively constitute a sub-pixel (Subpixel) for color display, and the three sub-pixels constitute one pixel (unit pixel: pixel) of the color display. The color filters CF-R, CF-G, and CF-B are respectively partitioned by a light shielding film (black matrix) BM, on which a counter electrode (common electrode) CT is formed, and an alignment film is formed on the innermost surface. (not shown) The liquid crystal alignment control energy such as rubbing treatment is applied to the alignment film, and the same alignment film is formed on the innermost surface of the TFT substrate SUB1, and the same liquid crystal alignment control energy is also applied. The lower polarizing plate p〇L1 and the undamaged plate POL2 are provided on the outer surfaces of the TFT substrate SUB! and the CF substrate SUB2. The upward arrow in FIG. 13 indicates white light emitted from a backlight (not shown). The substrate SUB1 and the CF substrate SUB2 are emitted as observation light. The liquid crystal layer LC is common to the sub-pixels of the full color, and the layer thickness of the liquid crystal layers of the respective colors, that is, the cell gap is the same. In this case, the transmittance of the sub-pixels j light transmittance τ is represented by the refractive index anisotropy Δη of the center wave m crystal of the transmission color of the sub-pixel and the layer thickness d of the liquid crystal layer. T=sin2{7iAn.d/^r} The light transmittance varies from pixel to pixel. Fig. 14 is a schematic view showing an example of light transmittance of each pixel device. The color filters CF-R 'CF-G and CF-B of different color pixels have different light transmittances. Let Δη of the liquid crystal be 0.0968, and the layer thickness of the liquid crystal layer LC be 2 85 _ of $14. The green pixel of the color chopper is provided, and the pixel of the work color is 94.5%, and the blue pixel is 87. 9%. The color of the three colors will change due to the difference in transmittance of the three colors. In the normally open mode, the white display should be colored yellow; in the normally closed mode, the black display should be colored. 2 Controlling the change of such chromaticity, the patent document [is proposed to make the layer thickness of the transparent insulating layer (top coat) of the pixel electrode and the color light device of each color different or to make the color of each color Further, Patent Document 2 proposes a multi-gap method in which the thickness of the glass substrate forming the pixel electrode of each pixel is changed.

Furthermore, it is difficult to set an appropriate An.d value for each pixel. Further, the method disclosed in Patent Document 2 is The thickness of the glass substrate of each pixel is changed, and the method increases the process for processing the glass substrate, and the step between the various thin or pixel electrodes and the top coat and the insulating film applied between the adjacent pixels is not easy to be fine. The first object of the present invention is to provide a liquid crystal display device which is capable of improving color reproducibility and contrast without changing the layer of the liquid crystal layer, and appropriately setting each color.

The wall of the partition wall Ρτ of the resin is disposed along the data line DL of the TFT substrate, and the screen printing is suitably used, but other methods such as the photolithography step may be used. In addition, the thickness of the partition wall in Fig. 4 and Fig. 5 is extremely thin in terms of its height. This is to emphasize the function as a wall, and in fact, its height corresponds to the cell gap, and can be sufficiently formed by coating by a screen printing method or the like. Also, the partition wall? 1 can also be formed on the side of the C F substrate. After the partition wall shown in Fig. 4 is formed, liquid crystal is applied to each pixel portion partitioned by the partition wall.

The same symbols as in Figure i correspond to the same parts. In addition, in Fig. 6, the alignment film, the counter electrode, and the like are also omitted. In the implementation m, the black matrix of the partition wall PT abutting on the CF substrate is separated from the adjacent pixel region. In the present embodiment, the black matrix portion on which the partition wall PT is disposed is removed, and the partition wall is directly abutted against the CF substrate. That is, if the cell gap is h, the south of the partition wall π is H > h. Fig. 7 is an explanatory view showing an example of a method of manufacturing a liquid crystal display device according to a second embodiment of the present invention.

The % of the circumference shows the thickness of the partition wall ρτ relative to 129638.doc 14 200907489 The reason why the twist is extremely thin is the same as in the first embodiment. The height of the partition wall PT is lower than the cell gap as illustrated in Fig. 6. The partition wall ρτ can also be formed sufficiently by coating by a screen printing method or the like. Further, the partition wall may be formed on the CF substrate side. As shown in Fig. 7, the above-mentioned (H_h) was formed to be high as compared with the example i. After the partition wall PT is formed, the liquid crystal is coated with the ink jet coating head IJH at each pixel portion partitioned by the partition wall. This coating method was the same as in Example 1. According to the second embodiment described above, it is possible to obtain a high-quality image display line crystal display device which suppresses the chromaticity change of the viewing angle and has a high contrast S. [Embodiment 3] Fig. 8 is a plan view showing a principal part of a third embodiment of a liquid crystal display device of the present invention. In the first embodiment and the second embodiment, as shown by the two arrows in FIG. 8, the pixels of the same color are arranged in the vertical direction (vertical direction) (see FIG. 3), and the arrangement direction of the pixels of the same color is arranged only between the arrays of adjacent pixels.

The i sub-pixel is formed in an area surrounded by the closed line team and the data line DL. In the embodiment}, each of the red, green, and blue pixels is arranged in the up and down direction of the same figure as indicated by the two arrows in the figure. In other words, color filter rows (R), (G), and (B) of the same color are arranged in the two directions of the two arrows. The outer ppAa and the left outer PPAb above and below the effective display area AR in J 4 are disposed with dummy pixels px_D which do not need to be injected into the liquid crystal. P is also disposed in the boundary portion between the PPAa and the PPAb in the area of the dummy pixel PX_D around the political display area, and the partition wall ρτ_Η in the left-right direction of the partition wall Ρτ-ν in the up-and-down direction does not cause the liquid crystal to leak.
