Problems solved by technology

But OCB liquid crystal display still has many shortcomings, as because the viscosity of liquid crystal composition is higher, refractive index is not too suitable, and the response time of display is slower, and viewing angle is not wide; Therefore, need to provide the viscosity of a kind of used liquid crystal composition, The refractive index is suitable, and the OCB liquid crystal display with fast response and good viewing angle can be achieved

Abstract

The invention relates to an OCB mode liquid crystal display (LCD). The LCD comprises an upper electrode plate, a lower electrode plate, and a liquid crystal layer, which is arranged between the upper electrode plate and the lower electrode plate. The liquid crystal layer comprises a liquid crystal composition with an OCB mode orientation; wherein the liquid crystal composition comprises the following compounds in percentage by the total weight of the liquid crystal composition: 10-65% of compound represented by the formula (I), 10-70% of compound represented by the formula (II), 0-40% of compound represented by the formula (III), 0-35% of compound represented by the formula (IV), and 0-35% of compound represented by the formula (V). The composition has the advantages of large optical anisotropy, low viscosity, proper dielectric anisotropy, wide nematic phase range, and good low-temperature inter-solubility.

Description

technical field [0001] The invention relates to a liquid crystal display, in particular to an optically compensated curved OCB mode liquid crystal display. Background technique [0002] Liquid crystal display (LiquId Crystal Display, LCD) has achieved rapid development due to its small size, light weight, low power consumption and excellent display quality, and has been widely used in portable electronic information products. As the size of LCD screens for portable computers, office applications, and video applications increases, several issues remain in order for LCDs to be used for large-screen displays and eventually to replace Cathode Ray Tube (CRT) displays need to be resolved. Such as improving viewing angle characteristics and improving response speed. The relatively narrow viewing angle of the LCD means that when it is observed away from the direction perpendicular to the normal line of the liquid crystal cell, the contrast drops significantly. For grayscale and co...
