Liquid-crystal displaying apparatus

Abstract

A first substrate includes, on one side thereof that is closer to a liquid crystal layer, a picture element electrode provided for each picture element region, a switching element, and a bus line. A second substrate includes a counter electrode opposing the picture element electrode. The picture element electrode includes a plurality of openings and a solid portion that includes a plurality of unit solid portions. In each picture element region, the liquid crystal layer takes a vertical alignment in the absence of an applied voltage, and forms a plurality of liquid crystal domains, each of which takes a radially-inclined orientation, in the plurality of openings and the solid portion by inclined electric fields produced at respective edge portions of the plurality of openings of the picture element electrode in response to an applied voltage. In each picture element region, at least one of the plurality of openings of the picture element electrode that is located along the bus line and located between two adjacent ones of the plurality of unit solid portions is superposed on the bus line.

Description

technical field [0001] The invention relates to a liquid crystal display device, in particular to a liquid crystal display device with wide viewing angle characteristics and capable of producing high-quality display. Background technique [0002] In recent years, thin and lightweight liquid crystal display devices are used as monitors for personal computers and displays for PDAs (Personal Digital Assistants). However, conventional twisted nematic (TN) type and super twisted nematic (STN) type liquid crystal display devices have a narrow viewing angle. Various technical developments have been employed to solve this problem. [0003] A typical technique for improving viewing angle characteristics of a TN or STN liquid crystal display device is to add an optical compensation plate thereon. Another method is to use the transverse electric field mode, in which a horizontal electric field is applied to the liquid crystal layer with respect to the plane of the substrate. A liqui...
