Abstract

The invention relates to a display substrate and a liquid crystal display panel, the display substrate is provided with a display area and a non-display area located on the periphery of the display area, the display substrate comprises an alignment film located in the display area, frame glue located in the non-display area and a retaining wall located between the alignment film and the frame glue, the retaining wall comprises a supporting part located in the non-display area and a first blocking part and a second blocking part which are formed on the supporting part and arranged at an interval, the second blocking part is located on the side, away from the alignment film, of the first blocking part, the height of the first blocking part is smaller than the film forming thickness of the alignment film, and the height of the second blocking part is larger than the film forming thickness of the alignment film. And a concave arc-shaped surface is formed on one side, facing the first blocking part, of the second blocking part. According to the display substrate, the problem that the edge thickness of the alignment film is not uniform can be solved, and narrow-frame or frameless design can be achieved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display substrate and a liquid crystal display panel. Background technique [0002] A liquid crystal display panel (LCD for short) includes an array substrate, a color filter substrate, and a liquid crystal layer located between the array substrate and the color filter substrate. Wherein, an alignment film is respectively formed on the inner side of the array substrate and the color filter substrate to guide the arrangement direction of the liquid crystal molecules. [0003] The alignment film solution is usually evenly coated on the array substrate or color filter substrate by printing plate transfer (APR) or inkjet printing (Inkjet Printing), and then heated and cured, aligned to form a film surface with a channel microstructure. for anchoring liquid crystals. However, in the actual production process, due to the effect of surface tension, the edge of the alignme...
