Problems solved by technology

However, conventional compensation films use optical compensation. Optical compensation adjusts the compensation value by stretching the film layer. Due to the limitation of film stretching, the compensation value is also limited, which cannot match the phase difference of the vertically aligned liquid crystal display device. Therefore, the vertical The effect of improving dark-state side-view light leakage of aligned liquid crystal display devices is limited

Abstract

The invention discloses a display device. The display device comprises a first polaroid and a second polaroid, a second polaroid, wherein the first polaroid and the second polaroid are oppositely arranged; the liquid crystal display panel is arranged between the first polaroid and the second polaroid; wherein the first polaroid comprises a first liquid crystal compensation layer and a first optical compensation layer; the second polaroid comprises a second liquid crystal compensation layer and a second optical compensation layer. On the basis that the birefringence property of liquid crystal molecules is symmetrically compensated by adopting the compensation film, the liquid crystal compensation layers are arranged on the first polaroid and the second polaroid, and the liquid crystal compensation layers regulate and control the compensation value through the refractive index difference and the thickness of the liquid crystal molecules, so that the adjustment range is large, and the limitation is small; the phase difference can be matched with high phase difference of a liquid crystal display panel; in addition, the two sides of the liquid crystal display panel are symmetrically arranged, the number of the film layers is consistent, the thickness is consistent, and the situation of bending caused by different stresses on the two sides of the liquid crystal display panel can be reduced.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display device. Background technique [0002] The side-view contrast of the existing vertical alignment liquid crystal display device is not good, thus affecting the image quality of the liquid crystal display device. In particular, with the development of high dynamic range image televisions, higher requirements are placed on the contrast ratio of liquid crystal display devices. Improving the contrast ratio of liquid crystal display devices is the development trend of the panel industry in the future. [0003] The poor side-view contrast of existing vertical alignment liquid crystal display devices is mainly caused by side-view light leakage in the dark state. As the viewing angle of the thin film transistor liquid crystal display device increases, the contrast of the picture will decrease continuously, and the definition of the picture will decrease. This is caus...
