It peels off from the liquid crystal and comes into contact with the transparent conductive layer 3 on the color filter 2, so that no voltage is applied to the liquid crystal. Therefore, as shown in FIG. 4, after forming a thin film transistor 14 on a substrate 5, an insulating protective layer 15 was formed.

点で問題が残った。Problems to be Solved by the Invention Color filters used in color liquid crystal display devices are formed of organic films. Therefore, the transparent conductive layer 3 formed thereon cannot be formed at elevated temperatures, making it difficult to form a high-quality film. For this reason, Figures 3 and 4
In the conventional configuration shown in the figure, moisture and ionic components contained in the color filters were released into the liquid crystal, resulting in problems in terms of poor operation and shortened lifespan.

This is an example of a high-contrast color liquid crystal display device in which the height of the color filter changes corresponding to Ft, G, and H, so that the gaps in which liquid crystal is injected are different for R, G, and B. Since the transparent conductive layer 3 on the filters 21L, 2b and the light-speed barrier layer 17 must be formed on an uneven surface, the ITO layer was formed by sputtering. Furthermore, SiNx' was formed as a transparent insulating layer 16.

Furthermore, the contrast as an image characteristic of the liquid crystal display has become 100 or more in terms of visibility. In addition, changes over time during actual operation of the device have also been reduced.
