Abstract

The invention provides a display panel and a manufacturing method thereof. The display panel includes: a first substrate and a second substrate oppositely arranged; a liquid crystal, the liquid crystal is arranged between the first substrate and the second substrate; a first alignment film, the first alignment film is arranged on the The surface of the first substrate close to the liquid crystal; the second alignment film, the second alignment film is arranged on the surface of the second substrate close to the liquid crystal, and is close to the second alignment film and the first alignment film respectively. The long axis of the liquid crystal molecules of an alignment film is opposite to the initial inclination direction of the plane where the first substrate is located. Therefore, the difference in effective liquid crystal retardation can be well compensated, thereby improving the color shift phenomenon, increasing the viewing angle, and improving the display quality, and because the transverse slit electrodes can still be used, the aperture ratio of the display panel will not be affected. .

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] In the existing display panels, the electrodes (common electrodes or pixel electrodes) usually use horizontal slit electrodes (slit electrodes), and the retardation of liquid crystals seen on the left and right sides is different, which will cause color shift and affect the display quality and customer satisfaction. The current improvement solution is to use vertical slit electrodes, but this approach will greatly reduce the aperture ratio. [0003] Therefore, research on improving the difference in retardation of liquid crystals needs to be further studied. Contents of the invention [0004] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. Therefore, an object of the present invention is to propo...
