Liquid crystal display device

Abstract

The invention discloses a liquid crystal display device which comprises an upper substrate, a lower substrate and liquid crystal molecules, wherein the liquid crystal molecules are arranged between the upper substrate and the lower substrate. The lower substrate comprises a first counter electrode, the upper substrate comprises a second counter electrode corresponding to the first counter electrode, the first counter electrode comprises a first pixel electrode and a first common electrode, the second counter electrode comprises a second pixel electrode and a second common electrode, and insulating layers are arranged between the first pixel electrode and the second common electrode and between the second pixel electrode and the second common electrode. According to the liquid crystal display device, warping of the liquid crystal molecules can be controlled when the device is in an opening state, penetration rate is increased, opening of the liquid crystal molecules is accelerate, response time of the liquid crystal molecules is shortened when the device is in a closing state, refractive index of liquid crystals is reduced based on invariant box thickness, so that the brightness of a dark state is reduced, and the contrast ratio of liquid crystal display is finally increased.

AI Technical Summary

Problems solved by technology

The response time of existing products is not fast enough, and the penetration rate needs to be improved. For example, in order to speed up the response time and reduce the thickness of the box, the refractive index must be increased, which will reduce the contrast. On the contrary, increasing the thickness of the box will slow down the response time, so it is urgent to improve the above performance
