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 optical compensation layer and a liquid crystal compensation layer; and the second polaroid comprises a second optical compensation layer. On the basis that the birefringence property of liquid crystal molecules is symmetrically compensated by using the optical compensation layer, the liquid crystal compensation layer is arranged on the first polaroid, the compensation value of the liquid crystal compensation layer is not increased through stretching, but is regulated and controlled through the refractive index difference and the thickness of the liquid crystal molecules, so that the adjustment range is large, and the adjustment precision is improved. The display device is small in limitation and can be matched with high phase difference of the display device, so that dark-state side-looking light leakage of the display device is further improved, the contrast ratio of the display device is improved, and the image quality is improved.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to a display device. Background technique [0002] The side-view contrast ratio of the existing vertical alignment liquid crystal display device is poor, thereby affecting the image quality of the liquid crystal display device. In particular, with the development of high dynamic range image televisions, there are higher requirements on the contrast ratio of liquid crystal display devices, and 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 ratio of the existing vertical alignment liquid crystal display device is mainly caused by the 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 is continuously reduced, and the definition of the picture is re...
