Abstract
The invention discloses a color film substrate and a manufacturing method thereof, a display panel and a display device, and belongs to the technical field of liquid crystal display. The color film substrate comprises an underlayer substrate body, a black matrix, a color resistor layer and a common electrode layer, the black matrix, the color resistor layer and the common electrode layer are arranged on the underlayer substrate body, a plurality of sub-pixel areas distributed in an array mode are defined by the black matrix on the underlayer substrate body, the color resistor layer comprises a plurality of color resistor blocks arranged on the sub-pixel areas in a one-to-one correspondence mode, and the common electrode layer is arranged on the black matrix and the color resistor layer. Spacer walls are arranged on the common electrode layer, each sub-pixel area is correspondingly provided with one spacer wall, and each spacer wall is of an annular structure surrounding the edge of the corresponding sub-pixel area. Conductive protruding foreign matter is blocked in pixels through the spacer walls of the annular structures, it is avoided that conductive wires on the underlayer substrate body and common electrodes on the color film substrate are connected to form poor bright lines, and the yield of TN type TFT-LCD products can be increased.
Description
technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a color filter substrate and a manufacturing method thereof, a display panel, and a display device. Background technique [0002] Thin Film Transistor Liquid Crystal Display (English: Thin Film Transistor Liquid Crystal Display, TFT-LCD for short) is a common flat panel display device at present, and is widely used. Generally, a TFT-LCD includes a color filter substrate and an array substrate arranged opposite to each other, and a liquid crystal arranged between the color filter substrate and the array substrate. [0003] Taking Twisted Nematic (English: Twisted Nematic, referred to as: TN) TFT-LCD as an example, the color filter substrate includes a plurality of color-resist blocks distributed in an array, a black matrix distributed between the color-resist blocks, and a color-resist covering The common electrode layer on the block and black matrix; the array sub...
