However, in JP-A-63-33730, the black light-shielding film is formed in the gap between the pixels by the printing method, and the size of each pixel is 200. .About.500 .mu.m, and the gap between each pixel is 20 to 30 .mu.m. It is extremely difficult to accurately align such a thin line by a printing method and print so as not to overlap each pixel. Further, when the alignment film is formed by the rubbing treatment after the formation of the light-shielding tank, if the protrusion as described above is provided, the alignment film is caught by the protrusion and broken, or the alignment film on the upper surface of each pixel is formed. There is a problem that it may not be possible.

In the liquid crystal panel of the present invention, a black light-shielding layer, which is thicker partially or entirely than the thickness of the color filter layer, is formed in the gap between the pixels of the color filter layer, and the black light-shielding layer is further spread on this. When a counter substrate provided with an electrode such as a TFT is attached by providing a spacer by, only the spacer on the light shielding layer is pressed and held between the substrates, and the spacer on the color filter layer stands upright on the liquid crystal panel. At this time, it passes through the liquid crystal between the substrates and falls downward. Therefore, by removing the spacers from the pixels formed of the color filter layer, it is possible to obtain a liquid crystal panel in which there is no abnormal alignment of liquid crystals due to the spacers and display obstruction due to the spacers themselves, and there are few omissions.
