Display substrate and display device

Abstract

A display substrate is provided, including a base substrate, an anode layer arranged on the base substrate, a pixel definition layer arranged at a side of the anode layer away from the base substrate and configured to define a plurality of pixels, and a plurality of pixel banks arranged on the pixel definition layer. The pixel definition layer and the plurality of pixel banks are arranged in such a manner as to divide each pixel into a plurality of subpixels. The pixel banks include first pixel banks each arranged between two adjacent subpixels in different colors, each first pixel bank is a line bank extending in a first direction, a light-emitting region for covering an anode of an OLED element and a non-light-emitting region outside the light-emitting region are arranged between two adjacent first pixel banks in a same pixel along the first direction, and an organic light-emitting layer barrier structure is arranged at the non-light-emitting region to reduce a difference between a thickness of an organic light-emitting layer at a periphery of the subpixel and a thickness of the organic light-emitting layer in the middle of the subpixel in a direction perpendicular to the base substrate. A display device is further provided.
