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 the second polaroid comprises a second liquid crystal compensation layer. According to the liquid crystal display panel, the liquid crystal compensation layers are arranged on the first polaroid and the second polaroid, the compensation value of the liquid crystal compensation layers is not increased through stretching, the compensation value is regulated and controlled through the refractive index difference and the thickness of liquid crystal molecules, and therefore the adjustment range is large, limitation is small, the liquid crystal display panel can be matched with the high phase difference of the liquid crystal display panel, and the display effect is good. Therefore, the dark-state side-looking light leakage of the liquid crystal display panel is further improved, the contrast ratio of the liquid crystal display panel is improved, and the image quality is improved. And the liquid crystal compensation layers are arranged on the two sides of the liquid crystal display panel, so that a better compensation effect is comprehensively achieved.

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...
