Abstract

The present disclosure provides a display substrate, a method of fabricating the same, and a display device. The display substrate comprises a base substrate including a display region and an open region adjacent to each other; and at least one isolation wall extending along a boundary between the display region and the open region, wherein each of the at least one isolation wall comprises at least one isolation structure, each of the at least one isolation structure comprises a first layer on a side of the base substrate and a second layer on a side of the first layer away from the base substrate, and the orthographic projection of the first layer on the base substrate is located inside the orthographic projection of the second layer on the base substrate. The isolation wall effectively blocks an organic light-emitting material, prevents moisture from entering the display region, and improves display quality.

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] As the screen-to-body ratio of display devices continues to increase, hole-digging screens have become an important solution to increase the screen-to-body ratio, especially OLED hole-digging screens. During the manufacturing process of the hole-digging screen, the organic light-emitting material around the hole easily absorbs moisture in the environment. The absorbed moisture will further infiltrate into the display area of ​​the screen through the organic light-emitting material, causing defects such as dark spots. Contents of the invention [0003] According to an aspect of the present disclosure, there is provided a display substrate, comprising: a base substrate including an adjacent display area and an opening area; and at least one display area extending al...
