The invention discloses a color film substrate of a display panel, a manufacturing method of the color film substrate and a display device. The color film substrate of the display panel comprises a substrate, a light shielding layer arranged on the substrate, and a plurality of retaining walls arranged on the light shielding layer of the color film substrate, wherein the light shielding layer is located in a non-display area of the substrate; the light shielding layer comprises a groove; the plurality of retaining walls are used for blocking the flowing of an alignment liquid; and the plurality of retaining walls are arranged perpendicular to the coating direction of frame glue of the display panel, and a height difference is formed between the plurality of retaining walls, wherein one retaining wall is arranged in the groove. The color film substrate is provided with the plurality of retaining walls which are gradually increased in height according to the flow direction of the alignment liquid; when the alignment liquid flows to the retaining walls, the alignment liquid can be blocked step by step, so that the alignment liquid is effectively prevented from flowing to the frame glue, and the frame glue is prevented from falling off; and then, the flow rate can be reduced every time when the alignment liquid flows through one retaining wall, so that the thickness increasing of the alignment liquid caused by backflow accumulation when the alignment liquid encounters the retaining walls due to the fact that the flow speed of the alignment liquid is relatively high can be avoided, so that the brightness of the display panel is more uniform.
Description
technical field [0001] The present application relates to the field of display technology, and in particular, to a color filter substrate of a display panel, a manufacturing method and a display device. Background technique [0002] In the field of Thin Film Transistor Liquid Crystal Display (TFT-LCD), a liquid crystal display panel is mainly composed of a color filter substrate, an array substrate, and a liquid crystal layer filled between the two substrates. Alignment films are arranged on the two substrates, and the liquid crystals can be aligned and arranged along the grooves on the alignment films, and the liquid crystals can be controlled by an electric field to form a display screen. The two substrates are fixed and installed by the frame sealant. Usually, a layer of alignment liquid (PI) is coated on the substrate to form a pre-tilt angle so that the liquid crystal has a fixed inversion during display. Alignment liquid is a fluid chemical liquid. After coating, it ...
