Liquid crystal display device

Abstract

Provided is a liquid crystal display device of VA mode having an excellent display quality. The liquid display device includes a pixel region having a first liquid crystal domain as a first direction, a second liquid crystal domain as a second direction, a third liquid crystal domain as a third direction, and a fourth liquid crystal domain as a fourth direction in which the tilt direction when voltage applied is decided in advance. The first, the second, the third, and the fourth directions are four directions, any two of which have direction difference of substantially 90 degrees multiplied by an integer. Moreover, the first, the second, the third, and the fourth liquid crystal domains are adjacent to other liquid crystal domains and are arranged in a matrix of two rows and two columns. A drain-extracting wire constitutes at least a part of a central light shielding portion for selectively light-shielding the boundary regions where each of the first, the second, the third, and the fourth liquid crystal domains is adjacent to the other liquid crystal domains. Moreover, at least one island-shaped light-shielding portion formed by the same layer as a gate bus line has a portion superimposed on the drain-extracting wire via a gate insulating film.

Description

technical field [0001] The present invention relates to a liquid crystal display device, in particular to a liquid crystal display device with wide viewing angle characteristics. Background technique [0002] The display characteristics of liquid crystal display devices have been improved, and their application to television receivers and the like is progressing. Although the viewing angle characteristics of liquid crystal display devices have been improved, further improvement is desired. In particular, there is a strong demand for improvement in viewing angle characteristics of a liquid crystal display device using a vertical alignment type liquid crystal layer (also referred to as a VA mode liquid crystal display device). [0003] Currently, VA-mode liquid crystal display devices used in large-scale display devices such as televisions adopt an alignment division structure in which a plurality of liquid crystal domains are formed in one pixel region in order to improve vi...

AI Technical Summary

Problems solved by technology

[0004] However, when using slits or ribs, unlike conventional TNs where the pretilt direction is defined by an alignment film, since the slits or ribs are linear, the force to restrict the alignment of liquid crystal molecules is limited to the pixel area. Inhomogeneous, therefore, there are problems such as distribution of response speed

In addition, the transmittance of light in the area where the slits or ribs are provided decreases, so there is also a problem that the brightness of the display decreases.
