Abstract

The invention relates to a display substrate, a preparation method therefor and a display device. The display substrate comprises a light-emitting part which is located in a display region of the display substrate; one or more dams which are located in a non-display region of the display substrate, wherein the non-display region surrounds the display region; and a first stress absorption part which disposed under at least one dam.

Description

technical field [0001] The present disclosure relates to the field of display technology, in particular to a display substrate, a manufacturing method thereof, and a display device. Background technique [0002] With the rapid development of display technology, people have higher and higher requirements for the performance of display products. As an important basis of a display device, a display substrate has attracted extensive attention. [0003] During the preparation process of the display substrate, cracks may appear on the encapsulation film layer of the display substrate during the cutting process, which may cause encapsulation failure and result in poor display. In the related art, trenches are prepared on the periphery of the display substrate to prevent cracks from cutting from spreading to the display area. Contents of the invention [0004] After research, the inventor found that grooves are prepared around the display substrate to prevent cracks during cutti...
