Abstract: In a wall electrode liquid crystal display device, planar distribution of the wall structure and the electrode is optimized to improve a yield. A liquid crystal display device includes a plurality of pixels arranged in a matrix, each of the pixels having an insulator wall structure formed at a border of pixels, a wall electrode formed at a side surface of the wall structure of the border of the pixels, a source electrode which is continuous with the wall electrode and formed of a planar electrode extending in a planar direction, a first common electrode provided between source electrodes at both sides of the pixel to form a retentive capacitance, and a second common electrode provided between wall electrodes on both sides of the pixel. A slit which becomes a border of the wall electrodes of two adjacent pixels is disposed only on a top of the wall structure.

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.
