Problems solved by technology

[0003] When the alignment fluid reaches the retaining wall, backflow accumulation will occur, resulting in an increase in the thickness of the alignment fluid, uneven display, or flow to the frame glue, causing the frame glue to fall off

Abstract

The invention discloses a substrate of a display panel, a manufacturing method of the substrate and a display device. The substrate comprises a substrate body, a light shield layer arranged on the substrate body and positioned in a non-display area of the substrate body, and different heights of retaining walls arranged on the light shield layer and set to block flow of an orientation liquid. Theretaining walls in tight connection are arranged in parallel to a frame glue coating method of the display panel. Thus, the retaining walls can retain the orientation liquid in different positions, the orientation liquid is prevented from diffusing to the frame glue position and making frame glue falling off; and if the retaining walls fail in blocking the orientation liquid, the orientation liquid can overflow out of a lower retaining wall uniformly.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a substrate of a display panel, a manufacturing method and a display device. Background technique [0002] In TFT-LCD (Thin Film Transistor Liquid Crystal Display, thin film transistor display device), the 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 provided on the two substrates, and the liquid crystals can be aligned and arranged along the grooves on the alignment films, and the liquid crystals are controlled by an electric field to form a display screen. The two substrates are fixed and installed by sealing glue. Usually, a layer of alignment liquid (PI) is coated on the substrate to form a pre-tilt angle to facilitate liquid crystals to have a fixed inversion during display. Alignment liquid is a kind of fluid chemical liquid, whi...
