Abstract

The invention discloses an array substrate, a display panel and a display device. The array substrate comprises a substrate, a color resistance layer and an alignment layer, wherein the substrate is correspondingly provided with a display area and a non-display area surrounding the display area; the color resistance layer comprises a first color resistance unit, a second color resistance unit and a retaining wall, the first color resistance unit is arranged in the display area, the second color resistance unit surrounds the outer side of the first color resistance unit in the circumferential direction, the second color resistance unit and the retaining wall are arranged in the non-display area, the retaining wall is arranged on the outer side of the second color resistance unit; the alignment layer is arranged on the side, away from the substrate, of the color resistance layer. The array substrate is advantaged in that thickness of the alignment layer on the outer side of the edge of the display area is increased, excessive alignment liquid is prevented from flowing to the low terrain when the alignment layer is prepared, the thinning degree of the alignment layer of the display area is reduced, film thickness of the alignment layer of the display area is relatively uniform, and a whitening phenomenon of the edge or the corner of the display area during reliability testing is reduced.

Description

technical field [0001] The present invention relates to the technical field of display devices, in particular to an array substrate, a display panel and a display device. Background technique [0002] In the manufacturing process of TFT (Thin Film Transistor, thin film transistor) display panel, an alignment layer is usually formed on the substrate (including the array substrate and the color filter substrate), and an orientation angle is formed on the alignment layer so that the liquid crystal molecules are aligned The orientation of the corners is pre-arranged. The orientation angle refers to an angle at which liquid crystal molecules are inclined along a substantially plane. One way to form the orientation angle is to rub the alignment layer with flannelette along a certain direction, so that microscopic grooves are formed on the surface of the alignment layer, and the long axes of the liquid crystal molecules will be aligned along the grooves to achieve the effect of pr...
