CROSS-REFERENCE TO RELATED APPLICATIONS

The present disclosure claims priority to Chinese Patent Application No. 202011612392.9, filed on Dec. 30, 2020, the content of which is incorporated herein by reference in its entirety.

TECHNICAL FIELD

The present disclosure relates to the field of display technologies, and more particularly, to a liquid crystal display panel and a display device.

BACKGROUND

With continuous development of display technology, liquid crystal displays have become commonly available products in the display industry. A liquid crystal display panel includes an array substrate, a color film substrate arranged opposite to the array substrate, and a liquid crystal layer disposed between the array substrate and the color film substrate. When the liquid crystal display panel is working, the orientation of the liquid crystal molecules changes under action of an electric field. Accordingly, an intensity of light passing through the liquid crystal molecules will change. Combining the effects of color resists of different colors in the color film substrate, the liquid crystal display panel displays an image having a desired color.

Currently, liquid crystal display panels have poor visual angle characteristics, and an extremely low contrast of the image when observed at a large visual angle. Therefore, a focus for researchers in this field lies in increasing contrast of the liquid crystal display panel observed at a large visual angle.

SUMMARY

In view of this, a liquid crystal display panel and a display device are provided according to embodiments of the present disclosure, to increase contrast of the liquid crystal display panel at a large visual angle.

Accordingly, in an aspect, a liquid crystal display panel is provided according to an embodiment of the present disclosure. In an embodiment, the liquid crystal display includes: a first substrate; a second substrate arranged opposite to the first substrate; a liquid crystal layer disposed between the first substrate and the second substrate; a first linear polarizer disposed at a side of the first substrate facing away from the liquid crystal layer; a first quarter-wave plate disposed between the first substrate and the first linear polarizer, an angle between a slow axis of the first quarter-wave plate and an absorption axis of the first linear polarizer being 45° or 135°; a second quarter-wave plate disposed between the liquid crystal layer and the first substrate, a slow axis of the second quarter-wave plate being perpendicular to the slow axis of the first quarter-wave plate; a second linear polarizer disposed at a side of the second substrate facing away from the liquid crystal layer, an absorption axis of the second linear polarizer being perpendicular to the absorption axis of the first linear polarizer; a first retardation film disposed between the first quarter-wave plate and the second quarter-wave plate; and a second retardation film disposed at a side of the first quarter-wave plate facing away from the first retardation film, or disposed between the second linear polarizer and the liquid crystal layer.

In another aspect, a display device including the liquid crystal display panel described above is provided according to an embodiment of the present disclosure.
