Abstract

An edge electric field switch type LCD device comprises a first basal plate, a second basal plate arranged oppositely to the first basal plate, as well as a liquid crystal layer clamped between the first basal plate and the second basal plate. A plurality of scan lines and a plurality of data lines are arranged on the second basal plate and are in insulated intersection to define a plurality of pixel units. A common electrode and a pixel electrode are stacked and arranged inside each pixel unit in an insulated mode. The common electrode is in a flat plate shape structure. A plurality of notches are alternately arranged inside the pixel electrode and distributed in a fan shape, and the angle between each notch and the scan lines gradually changes. The edge electric field switch type LCD device has higher penetration rate and better viewing angle characteristics.

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] Due to 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. Therefore, wide viewing angle technology has always been an important research topic for liquid crystal display technicians since the birth of liquid crystal display devices. [0003] Fringe Field Switching (FFS) technology is one of the mainstream wide-angle LCD technologies with considerable advantages. It was proposed by Hyu...
