Color film base plate and manufacturing method thereof as well as display panel and display device

Abstract

The invention discloses a color film base plate, a manufacturing method thereof, a display panel and a display device. The color film base plate comprises a substrate base plate, sub-pixel color resistors, black matrixes and a touch electrode layer, wherein the sub-pixel color resistors are arranged on the substrate base plate and are laid in an array manner; the black matrixes are arranged on the substrate base plate and are used for separating each sub-pixel color resistor; the touch electrode layer is arranged on the substrate base plate and is used as a flat layer; the touch electrode layer is segmented into multiple mutually insulating touch sensing electrodes; the orthographic projection, on the substrate base plate, of segmentation gaps between the touch sensing electrodes are located in an area where the black matrixes are located. According to the color film base plate which is provided by an embodiment of the invention, the touch electrode layer is used as the flat layer at the same time, so as to enable the color film base plate to have a touch function at the same time; the thickness and the weight of a display screen are reduced; and the yield loss caused in a process of abutting a touch screen and a liquid crystal display screen is avoided when an externally hung touch screen is used.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a color filter substrate, a manufacturing method thereof, a display panel and a display device. Background technique [0002] With the rapid development of display technology, touch screen panels (Touch Screen Panels) have gradually spread in people's lives. Currently, touch panels can be classified into: Add on Mode Touch Panel, On Cell Touch Panel, and In Cell Touch Panel according to their composition and structure. Among them, the plug-in touch screen is produced separately from the touch screen and Liquid Crystal Display (LCD), and then bonded together to form a liquid crystal display with touch function. The plug-in touch screen has high production costs and low light transmittance. Low, thicker modules and other disadvantages, and the touch screen and LCD screen are attached together by the plug-in type, which will increase the thickness and weight of the screen. Conte...
