Compensation film, manufacturing method thereof, and display device

Abstract

The present invention provides a compensation film, which includes a substrate and a liquid crystal material layer arranged on the substrate. The compensation film is divided into a plurality of compensation regions arranged in sequence along a predetermined direction, and the plurality of compensation regions include a plurality of A first compensation area and a plurality of second compensation areas, the first compensation area and the second compensation area are arranged alternately; the liquid crystal molecules of the liquid crystal material layer are inclined to the substrate; in the first compensation area The inclination directions of the liquid crystal molecules in the liquid crystal molecules and the liquid crystal molecules in the second compensation area are opposite. Correspondingly, the present invention also provides a method for manufacturing a compensation film and a display device. The compensation film of the present invention has a better viewing angle compensation effect, and can improve the contrast ratio of the display device side viewing angle.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a compensation film, a manufacturing method thereof, and a display device. Background technique [0002] With the continuous development of display technology, product specification requirements are getting higher and higher, and one of the important specification requirements is the side viewing angle contrast ratio. In liquid crystal products, due to the anisotropy of liquid crystal molecules, the contrast ratio decreases when the display screen is viewed from the side. Among them, the contrast is the ratio of the transmittance of the highest gray level to the lowest gray level. Usually, panel manufacturers will set a compensation film on the outside of the display panel for viewing angle compensation to increase the contrast of the side viewing angle. figure 1 It is a structural schematic diagram of a commonly used compensation film in the prior art, which includes a substr...

AI Technical Summary

Problems solved by technology

It can be seen that using figure 1 After the compensation film is compensated for the viewing angle, in position A (that is, the position where the viewing angle is 40° in the horizontal direction and about 20° in the vertical direction) and position B (that is, the viewing angle is -40° in the horizontal direction and about 20° in the vertical direction) Position), the contrast is low, therefore, the viewing angle compensation effect of the compensation film needs to be improved
