Problems solved by technology

However, with the gradual narrowing of the TFT-LCD panel frame, the distance between the edge of the frame glue and the cutting line is getting closer and closer, and it is easy to cause various serious problems in the subsequent process due to the overflow of the frame glue, such as overflow The final frame glue covers the alignment mark, making the subsequent alignment process difficult; and if the overflowed frame glue crosses the cutting line or sticks to the adjacent frame glue, which seriously affects the subsequent cutting process, it is easy to Poor breaking, liquid crystal leakage and other defects occur, resulting in the dilemma of high scrap rate

Abstract

The invention discloses a display substrate, a manufacturing method thereof and a display device, and belongs to the field of display. The display substrate comprises a display region and a frame adhesive applying region. The frame adhesive applying region is located outside the display region. A flow limiting organized array is arranged at the edge of the side, away from the display region, of the frame adhesive applying region. The flow limiting organized array comprises at least two adhesive containing grooves, and the adhesive containing grooves are formed in the direction away from the display region. Outward-overflowing frame adhesives are made to sequentially flow into the multiple adhesive containing grooves formed from interior to exterior, the flow limiting organized array can limit or block the frame adhesive from overflowing outwards, and the outer side structure is prevented from being covered with the frame adhesives, so that the influence caused by overflowing of the frame adhesives on the follow-up process is reduced, and the yield is improved.

Description

technical field [0001] The invention relates to the display field, in particular to a display substrate, a manufacturing method thereof, and a display device. Background technique [0002] Thin Film Transistor-Liquid Crystal Display (TFT-LCD) has become a mainstream product in the display field after several decades of development. Generally, in mobile display products, borders are defined from the display area to the edge of the display screen. The existence of the border will reduce the visual effect of the entire display screen, especially the larger the border area, the worse the visual effect. Therefore, narrow bezel or even bezel-less visual effects have become the mainstream trend of high-quality displays. [0003] In the display panel formed by dividing the display panel motherboard along the cutting line, the sealant surrounding the display area generally needs to be as far away from the cutting line as possible, so as to reserve enough allowable space for the ove...
