Abstract

The invention discloses a display panel. The display panel comprises a color film substrate, an array substrate opposite to the color film substrate and a liquid crystal layer located between the color film substrate and the array substrate, wherein a first alignment layer is arranged on the color film substrate; a second alignment layer is arranged on the array substrate; the first alignment direction of the first alignment layer is perpendicular to the second alignment direction of the second alignment layer; positive liquid crystal molecules in the liquid crystal layer are in a twisted arrangement state from bottom to top at the beginning; the color film substrate is also provided with a first orientation layer and a first visual angle compensation layer; the first orientation layer isused for orienting the first visual angle compensation layer, and the first orientation direction of the first orientation layer is reversely parallel to the first alignment direction of the first alignment layer; the array substrate is further provided with a second orientation layer and a second visual angle compensation layer, the second orientation layer is used for orienting the second visualangle compensation layer, and the second orientation direction of the second orientation layer is reversely parallel to the second alignment direction of the second alignment layer. The invention discloses a manufacturing method and a display device.

Description

technical field

[0001] The invention relates to the technical field of liquid crystal display, in particular to a display panel, a manufacturing method and a display device. Background technique

[0002] A TN type (ECB type or OCB type, etc.) liquid crystal display device has a very narrow viewing angle (about 40°) due to its own liquid crystal arrangement. In order to compensate for the viewing angle, the most common method at present is to coat (Coating) a layer of discotic liquid crystal molecules (DLC) on the polarizer by FujiFilm Company of Japan. By aligning the orientation of the DLC with the liquid crystal molecules in the liquid crystal cell (Liquid crystal, LC for short) are anti-parallel in orientation, thereby widening the viewing angle (from about 40° to about 80°). Or, by attaching a viewing angle compensation film, that is, using a wide viewing angle compensation film for compensation (mainly using a polymer material with negative birefringence such as discot...
