Abstract

A fringe electric field switching type liquid crystal display device, which includes a first substrate, a second substrate opposite to the first substrate, and a liquid crystal layer sandwiched between the first substrate and the second substrate, the A plurality of scanning lines and a plurality of data lines are arranged on the second substrate, and the plurality of scanning lines and the plurality of data lines are insulated and intersect to define a plurality of pixel units, and a common electrode and a pixel electrode are stacked and insulated in the pixel unit, and the common electrode and the pixel electrode are arranged in isolation. The electrode is in the shape of a plate, and a plurality of cutouts are arranged at intervals in the pixel electrode, and the cutouts are distributed in a fan shape, and the angle between each cutout and the scanning line changes gradually. The fringe electric field switching type liquid crystal display device has higher transmittance and better viewing angle characteristics.

Description

Technical field [0001] The present 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 becoming more widely used, and with the maturity and innovation of related technologies, their types are also increasing. Generally, when the user views the liquid crystal display device from different angles, the contrast of the screen will decrease as the viewing angle increases, which results in viewing angle limitations. Therefore, since the birth of liquid crystal display devices, wide viewing angle technology has always been an important research topic for liquid crystal display technicians. [0003] Fringe Field Switching (FFS) technology is one of the mainstream wide-view LCD technologies with considerable advantages. It was proposed by Hyundai Cor...
