Description

【Technical field】 [0001] The present invention relates to a liquid crystal display device, in particular to a fringe field switching (Fringe Field Switching, FFS) liquid crystal display device. 【Background technique】 [0002] Due to the characteristics of low radiation, light and thin volume and low power consumption, liquid crystal display devices are widely used, and with the maturity and innovation of related technologies, there are more and more types of liquid crystal display devices. [0003] Generally, when the user views the liquid crystal display device from different angles, the contrast of the image will decrease as the viewing angle increases, which is the viewing angle defect of the liquid crystal display device. In order to overcome the defects of narrow viewing angles in the twisted nematic and super twisted nematic liquid crystal display devices that appeared earlier, Hitachi of Japan firstly proposed a wide-ranging In-Plane Switching Mode (IPS) viewing angl...
