Problems solved by technology
[0003] The periphery of the display area is the boundary of the AA area (Active Area, display area) from the inside to the outside, the PI boundary, and the sealant boundary, and the PI coating process is prone to reflow and diffusion phenomena, and it is easy to cause the PI boundary to be far from the AA area during reflow. The border is too close, and shadows appear around the AA area; the border of PI is too close to the border of the sealant during diffusion, and the overlap of PI and sealant leads to poor adhesion of the sealant

The invention discloses an array substrate, a manufacturing method of the array substrate, and a display panel. The array substrate comprises a display area and a non-display area; the array substratecomprises a base substrate, a sealant area for coating the sealant is arranged on the base substrate, the sealant area is located at the non-display area; the array substrate further comprises a black matrix layer, wherein the black matrix layer comprises a first black matrix region and a second black matrix region; the second black matrix region is arranged between the display area and the sealant area, a spill-proof convex rib and a spill-proof groove are formed on the second lack matrix region; the spill-proof convex rib is arranged between the display area and the sealant area, and the spill-proof groove is arranged at one side, close to the display area, of the spill-proof convex rib; an alignment layer arranged at a location, corresponding to the display area, of the first black matrix region, wherein the spill-proof convex ring is arranged by surrounding the alignment layer. The technical scheme disclosed by the invention aims at preventing the alignment layer from closing to the boundary of the display area or closing to the sealant in the manufacturing process, the shadow at the boundary of the display area is avoided, and the adhesive force of the sealant is prevented from getting worse.
Description
technical field [0001] The present invention relates to the technical field of display panel packaging, in particular to an array substrate, a manufacturing method of the array substrate and a display panel. Background technique [0002] A liquid crystal display panel (Liquid Crystal Display, LCD) is widely used due to many advantages such as a thin body, power saving, and no radiation. Most of the liquid crystal display panels currently on the market are backlight type liquid crystal display panels, which include a liquid crystal display panel and a backlight module. Usually, a liquid crystal display panel is composed of a color film substrate, a thin film transistor substrate, a liquid crystal between the color film substrate and the thin film transistor, and a sealant; usually, there is a layer of alignment film on the thin film transistor substrate and the color film substrate. After the film is in contact with the liquid crystal, it can cause the liquid crystal to prod...
