ったり、輪郭がぼけて見えるという欠点を有していた。Configuration of Conventional Example and Its Problems Conventionally, a liquid crystal display device that outputs a predetermined color by a color filter has a liquid crystal display panel 1 as shown in FIG.
A predetermined color filter 2 is installed on the back surface of the liquid crystal panel, and the liquid crystal in the liquid crystal display panel 1 is used as an optical shutter. It is a structure that is attached. 3 is a light source. However, in the color filter 2, as shown in FIG. 2, since the color regions 2a to 2d of red, blue, etc. are arranged in a plane, the color regions 2a to 2d are slightly obliquely observed. There was a defect that the adjacent colors were visible at the boundary and the colors were misaligned, or the outline was blurred.
この欠点をより詳細に説明するとつぎのとおりである。
すなわち、第３図に示すように、液晶表示パネル１は、

７が観測すると、その色領域2cの他に隣りの色領域2bが
一定幅で見えることになり、このため色ずれ，色の輪郭
ぼけ現象が生じることとなる。This drawback will be described in more detail as follows.
That is, as shown in FIG. 3, the liquid crystal display panel 1 is
A liquid crystal layer 6 is arranged between the front glass 4 and the back glass 5. The liquid crystal layer 6 is formed by partitioning a plurality of liquid crystal regions 6a to 6e corresponding to the respective color regions 2a to 2e of the color filter 2, and electrodes (not shown) are provided corresponding to the respective liquid crystal regions 6a to 6e. . Now, if an electric field is applied to only one liquid crystal region 6c so that it has a light-transmitting property, when viewed from the front, only the color region 2c of the color filter 2 corresponding to that liquid crystal region 6c can be seen. As shown in FIG. 3, when the observer 7 observes from an oblique direction, the adjacent color area 2b can be seen with a constant width in addition to the color area 2c, which causes color shift and color outline blur phenomenon. Will occur.
そこで、これを緩和する方法として、第４図に示すよう
に、カラーフィルタ２′の各色領域2a′〜2e′の境界部
分に一定幅のブラックストライプ領域８を設ける提案が
なされた。しかし、このような方法では、上記問題を少
しは緩和できるものの、大きな効果を得ようと思えば、
ブラックストライプ領域８の幅を広くとる必要があり、
その幅を広くとると、全体の正面よりの開口率（各色領
域2a′〜2e′の面積）がかなり減少するという新たな問
題が生じる。Therefore, as a method of alleviating this, it has been proposed to provide a black stripe region 8 having a constant width at the boundary between the color regions 2a'-2e 'of the color filter 2', as shown in FIG. However, although such a method can alleviate the above problems a little, if one wants to obtain a great effect,
It is necessary to make the width of the black stripe region 8 wide,
If the width is widened, a new problem arises in that the aperture ratio (the area of each color region 2a 'to 2e') from the front is considerably reduced.

がら、色ずれ，輪郭ぼけ現象を解消できる液晶表示装置
を提供することである。OBJECT OF THE INVENTION An object of the present invention is to provide a liquid crystal display device capable of eliminating the color shift and the blurring of the contour while suppressing the reduction of the aperture ratio from the front.

同一部分に同一符号を付してその説明を省略する。Description of Embodiments One embodiment of the present invention will be described with reference to FIGS. 5 and 6. FIG. 5 shows an example of the color filter 10 having the black light shielding wall 9. In the figure, the color filter 10 having each color region 10a to 10d of red, blue, green, yellow, etc. is a flat plate, and has a constant width and height at the boundary of each color region 10a to 10d. A black light shielding wall 9 is provided. These configurations are the same regardless of the colors of the color regions 10a to 10d.
As shown in FIG. 6, a color filter 10 'having the same structure as the color filter 10 is provided in each color area 10a'-10
e'is arranged corresponding to each liquid crystal region 6a to 6e of the liquid crystal panel 6. Other configurations are the same as the conventional example,
The same parts are designated by the same reference numerals and the description thereof will be omitted.

小さくでき、正面よりの開口率の減少も少なくできる。As a result of such a configuration, for example, in the case where only the liquid crystal region 6c is provided with an electric field so as to have a light-transmitting property, even if the observer 7 observes from an oblique direction, the black light shielding wall 9 causes the adjacent color regions to be adjacent to each other. 10b 'is not visible, only the color area 10c' corresponding to the liquid crystal area 6c is visible, and the color shift and the blurring of the outline can be eliminated. Moreover, since the black light shielding wall 9 is projected forward of the surface of the color filter 10 ', the black light shielding wall 9
Can be made smaller than the width of the black stripe region 8 of the above-mentioned proposed example, and the reduction of the aperture ratio from the front can be reduced.
