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.
Abstract translation: 在液晶显示装置中，在对置基板上依次形成遮光膜，滤色器，外涂膜和取向膜。 然而，取向膜不形成在密封部中。 当利用紫外线照射取向膜时，未被取向膜覆盖的外涂层的一部分被紫外线照射而劣化。 为了防止从劣化的外涂膜渗透的水分到达遮光膜，从而改变遮光膜，并且不会引起遮光膜的剥离，滤色器设置在外涂膜的下方以阻挡水分。
