Abstract

In a liquid crystal display device of the present invention, when a display voltage is applied to picture element electrodes, each picture element electrode forms a plurality of domains in which liquid crystal molecules align themselves in different directions. The picture element electrodes are formed such that their edge portions on the opposite sides of a picture-element-electrode aperture portion formed between the picture element electrodes face parallel to each other with a certain interval. A source bus line is provided along the picture-element-electrode aperture portion formed between the picture element electrodes. The source bus line is disposed beneath the picture element electrodes and at the edge portions of the picture element electrodes by overlapping therewith in a direction of thickness.

Description

[0001] This Nonprovisional application claims priority under 35 U.S.C. § 119(a) on Patent Application No. 2003 / 209340 filed in Japan on Aug. 28, 2003, the entire contents of which are hereby incorporated by reference. FIELD OF THE INVENTION

[0002] The present invention relates to a liquid crystal display device and, more particularly, to a liquid crystal display device of a so-called multi-domain vertical alignment mode. BACKGROUND OF THE INVENTION

[0003] Conventionally available are liquid crystal display devices of a VA (Vertical Alignment) mode using a vertical alignment film, offering good contrast, good working speed, and good viewing angle characteristics. In recent years, in order to increase viewing angle, there has been developed a multi-domain technique, in which a display pixel is divided into a plurality of domains and the alignment of liquid crystal is varied in these domains.

[0004] There are mainly two kinds of substrate structure which can realize such a multi-domain...
