Abstract:
1. A lateral electric field liquid crystal display device, comprising: a substrate; a planar electrode formed in a planar form on the substrate; strip electrodes formed in a strip form on the planar electrode via an insulating film; and a liquid crystal aligned substantially in parallel to the substrate, the liquid crystal display device controlling a display by rotating the liquid crystal within a plane substantially in parallel to the substrate by an electric field between the planar electrode and the strip electrodes, wherein: each pixel constituting the display is divided into a first region and a second region; an extending direction of a strip electrode of the first region and an extending direction of a strip electrode of the second region are orthogonal; an alignment azimuth of the liquid crystal of the first region at a time when an electric field is not applied and an alignment azimuth of the liquid crystal of the second region at the time when the electric field is not applied are orthogonal; an angle formed between the extending direction of the strip electrode in the first region and the alignment azimuth of the liquid crystal at the time when the electric field is not applied and an angle formed between the extending direction of the strip electrode in the second region and the alignment azimuth of the liquid crystal at the time when the electric field is not applied are the same; the alignment azimuth of the liquid crystal of the first region at the time when the electric field is not applied is perpendicular to a data line and the alignment azimuth of the liquid crystal of the second region at the time when the electric field is not applied is parallel to the data line; and the strip electrodes extend in oblique directions with respect to the data line.
