Abstract

The invention discloses a liquid crystal display device comprising a plurality of liquid crystals, a switch element, a plurality of alignment films and a plurality of electrodes. The switch element is provided with a directional top and forms an electric field by a grid electrode, a drain electrode and a source electrode; the alignment films are positioned on a pixel, and corresponds to the directional top of the switch element, wherein when the plurality of the electrodes of the switch element form an electric field, the plurality of the liquid crystals are arranged along the alignment direction top and point to the directional top by the dint of the electric field, so that the electric field ability is enhanced, and the response speed of liquid crystal is increased.

Description

Technical field [0001] The invention relates to a liquid crystal display device, and more particularly to a liquid crystal display device with switching element design pixels. Background technique [0002] In recent years, liquid crystal display devices (LCDs) have been widely used in electronic products due to their advantages of lightness, thinness, low radiation, low power consumption, etc., and have gradually replaced traditional cathode tube rays (CRT). The liquid crystal display device uses the rotation of the liquid crystal to control the transmittance of the display device. It is necessary to use wide viewing angle technology to improve the shortcomings of the narrow viewing angle. The increase in the viewing angle will cause the contrast drop and grayscale error. In the future, the development of large-scale liquid crystal display devices will be accompanied by the above problem. [0003] Liquid crystal does not belong to the general three-state classification, solid, li...
