Abstract: In a liquid crystal display device including: TFT substrate; color filter; counter electrode; interlayer insulation film; pixel electrode; alignment film; liquid crystal layer; counter substrate; and Si semiconductor layer. The color filter, counter electrode, interlayer insulation film, pixel electrode, and alignment film being formed on the side where the TFT substrate is provided, the counter substrate being disposed in facing relation to the TFT substrate with the liquid crystal layer put between the counter substrate and TFT substrate, the Si semiconductor layer is formed between the pixel electrode and interlayer insulation film. Even when light from a backlight is absorbed by the color filter and sufficient light cannot reach the alignment film, electric charges accumulated on the alignment film can escape to the pixel electrode in an early stage by the Si semiconductor layer formed under the alignment film, thereby capable of erasing the afterimage in an early stage.

Abstract: In a liquid crystal display device, a light shielding film, a color filter, an overcoat film, and an alignment film are formed in this order on a counter substrate. However, the alignment film is not formed in a seal portion. When the alignment film is subjected to photo-alignment with ultraviolet radiation, a portion of the overcoat film not covered with the alignment film is degraded by ultraviolet radiation. In order to prevent moisture penetrating from the degraded overcoat film from reaching the light shielding film to thereby alter the light shielding film and from causing the peeling of the light shielding film, the color filter is disposed below the overcoat film to block the moisture.
