Problems solved by technology

[0007] However, the pixel electrode of the dual-area fringe electric field switch type liquid crystal display device is in the shape of a zigzag line (namely "<" shape), and has a sharp bent part (ie, the corner of the "<" shape). , due to the abnormal electric field, the liquid crystal molecules in this place are deflected and disordered, resulting in rotation displacement (Disclination), which reduces the color quality

Abstract

The invention discloses an edge electric field switch-type LCD device, which comprises a clearing upper basement, a clearing down basement, a liquid crystal liquid, multiple brake cables and data wire. The liquid crystal liquid is between upper and down basements; multiple brake cables and data wire form array pixel unit on basement; every pixel unit comprises pixel electrode and public electrode; the public electrode is panel shape, and the pixel electrode presents curve form with at least part.

Description

【Technical field】 [0001] The invention relates to a liquid crystal display device, in particular to a fringe electric field switch type liquid crystal display device. 【Background technique】 [0002] Because of the characteristics of low radiation, thin thickness and low power consumption, liquid crystal display devices are widely used, and with the maturity and innovation of related technologies, their types are also becoming more and more diverse. Generally, when the user views the liquid crystal display device from different angles, the contrast of the image will decrease with the increase of the viewing angle, thereby resulting in a limited viewing angle. Fringe Field Switching (FFS) technology is a solution based on the narrow viewing angle of traditional liquid crystal displays. It differs from In-Plane Switching (IPS) wide viewing angle technology in that fringe field switching The technology places the common electrode under the pixel electrode as a whole with a tran...
