Abstract

The invention discloses a liquid crystal display, comprising from the top down: upper polarizer, upper substrate, upper transparent conducting layer, liquid layer, lower transparent conducting layer, lower substrate and lower polarizer, composing a stacked structure, where the liquid crystal layer is directly placed in between the upper and lower transparent conducting layers and directly adjacent to them; the transparent conducting layers are of indium tin oxide and their sheet resistances are 5-25 ohm / sheet; the liquid crystal layer is composed of nematic liquid crystal doped chiral spiral agent, where the spiral structure of the liquid crystal is between 260 and 280 deg, and optical delay valve of the spiral structure is 1.06-1.35. And it can not adopt oriented layer, thus raising the response speed; simplifying the wording procedure and saving cost of materials.

Description

【Technical field】 [0001] The invention relates to a liquid crystal display. 【Background technique】 [0002] In the display characteristics of liquid crystal displays with twisted nematic structure and super twisted nematic structure, the response speed is generally above 50 milliseconds. This response speed has a certain tailing phenomenon in displaying dynamic images. Super twisted direction The response speed of the column phase is relatively slower. [0003] The traditional solution is to improve the liquid crystal material and reduce the thickness of the liquid crystal layer. However, due to the inherent characteristics of liquid crystal materials, it is very difficult to optimize parameters. It is difficult to find the best solution between the dielectric constant, elastic constant, and viscosity of liquid crystals and the physical structure and physical properties of the material. Therefore, improving materials Little progress has been made in this area, and the focu...
