Abstract
A display device is provided. In the present application, a liquid crystal compensation layer is provided on both first polarizer and second polarizer, and an improvement of compensation value is not realized by stretching the liquid crystal compensation layer but by adjusting the refractive index difference and thickness of the liquid crystal molecules, so the adjustment range is large, the restriction is small, and it can be matched with the high phase difference of the liquid crystal display panel. Therefore, the dark state side-view light leakage of the liquid crystal display panel and the contrast ratio of the liquid crystal display panel are improved, and the image quality is enhanced.
