Vertical orientation liquid crystal display

Abstract

The embodiment of the invention discloses a vertical orientation liquid crystal display, wherein a vertical orientation type liquid crystal layer is injected between an upper layer glass substrate and a lower layer glass substrate; the interior of the vertical orientation type liquid crystal layer comprises liquid crystal with negative anisotropy and a dielectric constant and plastic balls used for supporting; an upper layer conductive electrode is arranged on the lower surface of the upper layer glass substrate, and a lower layer conductive electrode is arranged on the upper surface of the lower layer glass substrate; an upper orientation layer is arranged between the upper layer conductive electrode and the vertical orientation type liquid crystal layer, and a lower orientation layer is arranged between the lower layer conductive electrode and the vertical orientation type liquid crystal layer; an upper layer circular polaroid is arranged on the upper surface of the upper layer glass substrate, and a lower layer circular polaroid is arranged on the lower surface of the lower layer glass substrate; a phase compensation value Delta n*d of the upper layer circular polaroid and the lower layer circular polaroid ranges from 110 nm to160 nm; and a refractive index of the upper layer circular polaroid and the lower layer circular polaroid in Z direction ranges from 1.4 to 1.8.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a vertical alignment liquid crystal display. Background technique [0002] With the rapid development of the global automobile industry and the continuous update and change of consumer concepts in the automobile market, as liquid crystal display products develop increasingly rapidly, people's requirements for the performance of displays used in vehicle display devices have greatly increased. [0003] In the prior art, the liquid crystal display usually used for vehicle-mounted display devices mainly includes the following structure: an upper transparent substrate and a lower glass substrate, a liquid crystal layer is poured between the upper and lower transparent substrates, and the outer layer of the upper and lower transparent substrates Wired polarizers are respectively attached on the surface. The inventors of the present invention found in the process of real...

Problems solved by technology

The inventors of the present invention found in the process of realizing the present invention that linear polarizers are respectively attached to the outer surfaces of the upper and lower transparent substrates in the prior art, and determined by the characteristics of the linear polarizers themselves, this liquid crystal The light transmission performance of the display is poor, and the display effect is poor, and this liquid crystal display with poor display effect is applied to the vehicle-mounted display device, and the vehicle-mounted display device itself often bumps and sways with the car, and its display The performance will become worse. For this reason, developing a liquid crystal display with high display performance has become an urgent and hard-working development goal of various liquid crystal display device manufacturers.
