Abstract:
1. A liquid crystal display device comprising: a scanning line over a substrate; a signal line intersecting the scanning line over the substrate; a ridge; a first pixel electrode; a second pixel electrode; an opposed electrode over the first pixel electrode and over the second pixel electrode; a liquid crystal between the first and second pixel electrodes and the opposed electrode, and an oriented film between the first and second pixel electrodes and the liquid crystal; and a driver configured for driving the first pixel electrode and the second pixel electrode at different polarities with respect to the opposed electrode, wherein the first pixel electrode is adjacent to the second pixel electrode with at least one of the scanning line and the signal line interposed therebetween, wherein the first pixel electrode contains a main face, and a first face closer to the opposed electrode than the main face, wherein the first face is disposed over the ridge, wherein a section of a crest of the ridge is curved, wherein the section is perpendicular to the substrate, wherein the first face is extended along one of the scanning line and the signal line, and wherein the rubbing direction of the oriented film is along the scanning line.
