Problems solved by technology

However, in the production of curved liquid crystal display panels, the biggest problem is that the color filter substrate and the array substrate are offset when they are bent, which will cause the black matrix to be unable to completely cover the transmitted light, resulting in a decrease in picture quality
In order to overcome this problem, the usual method is to widen the black matrix design, but this design often greatly reduces the transmittance, and needs to increase the backlight to achieve the brightness required by the product, which will greatly increase the product cost and power consumption.

Abstract

The invention discloses a color film substrate, a display panel and a display device. The color film substrate comprises a base substrate, a colored filter layer and a phase reversal pattern, wherein the colored filter layer and the phase reversal pattern are arranged on the base substrate, the phase reversal pattern comprises multiple openings, the multiple openings correspond to multiple filter units of the colored filter layer, and the phase reversal pattern is used for defining the boundary of each filter unit; the projection of the phase reversal pattern on the base substrate is at least partially covered on the projection of an area between adjacent filter units on the base substrate; and the phase reversal pattern is configured for enabling light passing through the phase reversal pattern to generate phase reversal. The color film substrate can replace or partly replace a black matrix by forming the phase reversal pattern on the base substrate, and due to the adoption of the color film substrate, the generation of light leak caused by bending, of the display panel, can be prevented.

Description

technical field [0001] At least one embodiment of the present invention relates to a color filter substrate, a display panel, a manufacturing method thereof, and a display device. Background technique [0002] With the development of display technology, liquid crystal display panels are widely used in various display devices, such as mobile phones, watches, computers, tablet computers, and televisions. The basic structure of the liquid crystal display panel includes an array substrate (Array Substrate) and a color filter substrate (ColorFilter Substrate), and a liquid crystal (Liquid Crystal) layer sandwiched between the two substrates. In the liquid crystal display panel, the black matrix (BlackMatrix, BM) is a very important component, and its basic function is to shield light, avoid light leakage and color mixing between sub-pixels, so as to achieve the purpose of improving contrast and reducing external light reflection. [0003] On the other hand, with the pursuit of h...
