Abstract

The invention relates to a multi-domain vertical orientation mode liquid crystal display device. The liquid crystal display device comprises a colorful film basal plate and an array basal plate, wherein each pixel on the array basal plate comprises a first pixel electrode and a second pixel electrode which are connected with a current line grid line through a first thin film transistor and a second thin film transistor respectively. Each pixel also comprises a third thin film transistor; a grid of the third thin film transistor is connected with a next line grid line; a drain electrode is connected with the second pixel electrode; and a source electrode is connected with a current line common electrode line. The aspect ratio of the first or second thin film transistor is higher than thatof the third thin film transistor. The multi-domain vertical orientation mode liquid crystal display device can improve the side visibility without impacting the opening rate.

Description

technical field [0001] The invention relates to a multi-domain vertical alignment mode liquid crystal display device, in particular to a multi-domain vertical alignment mode liquid crystal display device with improved lateral visibility. Background technique [0002] With the continuous advancement of liquid crystal flat panel display technology, liquid crystal display devices are being widely used in various fields, such as mobile phones, desktop computers, television sets, notebook computers and the like. High-end liquid crystal displays are developing in the direction of high contrast, wide viewing angle, fast dynamic response, and wide color gamut. [0003] Among them, the viewing angle problem has always been an important problem that plagues the development of liquid crystal displays. In order to solve this problem, one of the mainstream technologies currently used is to divide the liquid crystal into multiple blocks, so that the liquid crystal molecules in different ...
