Abstract

The invention discloses a display panel, a manufacturing method and a display device. The display panel is divided into a display area and a non-display area, and comprises a first substrate, a secondsubstrate opposite to the first substrate, frame glue corresponding to the non-display area and arranged between the first substrate and the second substrate, and an alignment layer arranged on the second substrate; the non-display area of the second substrate is provided with a retaining wall structure; the retaining wall structure is arranged between the alignment layer and the frame glue; theretaining wall structure comprises a trunk and a plurality of branches; the branches are at least arranged on one side, close to the alignment layer or the frame glue, of the trunk; and the branches are far away from the trunk and extend to the alignment layer or the frame glue. The retaining wall structure comprises the trunk and the branches, so that when the frame glue or an alignment liquid forming the alignment layer impact a retaining wall, the frame glue or the alignment liquid can be distributed; and therefore, the possibility that the frame glue or the alignment liquid is excessivelyaccumulated and goes beyond the retaining wall structure to be overlapped is reduced, and the display quality can be displayed.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a manufacturing method and a display device. Background technique [0002] Display panels, such as thin film transistor liquid crystal displays (Thin Film Transis-tor-Liquid Crystal Display, TFT-LCD), before TFT-LCD is filled with liquid crystals, it usually needs to be patterned on the patterned array substrate (Thin Film Transistor, TFT ) and a color filter substrate (Color Filter, CF) are first coated with a layer of polyimide (Polyimide, PI) to generate an anchoring force on the liquid crystal, so that the liquid crystal has a fixed pretilt angle. [0003] When PI is applied to the substrate, it is a liquid, and the PI film can only be formed after drying. In order to avoid the overlapping of the PI liquid and the frame glue (Overlap) and the poor curing effect of the frame glue, a spacer (Photo Spacer) is usually designed on the CF side during desig...
