Abstract: In an orientation division type liquid crystal display device for widen a viewing angle of a display pixel of an active matrix type liquid crystal color display device having a COT structure, pixel color layers (6B, 6R, 6G) as color filters and pixel electrodes 3 are formed on a substrate on the side of the pixel electrodes and slopes 13 are provided along four side peripheries of each pixel electrode. Liquid crystal molecules 8 between each pixel electrode of the pixel electrode substrate and a common electrode of an opposing substrate are controlled in orientation direction along the slopes to divide it to a plurality of directions to thereby widen a viewing angle of a pixel display. The slope is formed on a step portion 12 formed by a BM layer formed on at least one of a gate electrode, a drain electrode and a source electrode formed in a periphery of the pixel electrode or at least one of a gate wiring and a drain wiring formed in the periphery or a step portion formed by partially overlapping peripheral portions of the adjacent pixel color layers.

Abstract: A multi-domain alignment liquid crystal display device in which liquid crystal molecules are aligned through a simple process and panel gap is maintained in stable fashion includes a first plate having a thin-film transistor provided at each point of intersection of a scanning line and signal line, a pixel electrode connected to the thin-film transistor and a first orientation layer formed on the pixel electrode and defining a curved surface, and a second plate having RGB color layers, an counterelectrode provided so as to oppose the pixel electrode, and a second orientation layer. A columnar spacer for regulating the panel gap is provided between the two opposing plates, and liquid crystal is sandwiched between the two plates and subjected to multi-domain alignment by the first orientation layer having the curved surface and the columnar spacer.
