Abstract

A display substrate and a display device are provided. The display substrate includes: a base substrate, a pixel driving circuit layer, a first planarization layer, an anode layer, a light emitting functional layer, and a spacer. The first planarization layer includes a first via hole, the anode layer includes a first anode and a second anode, the first anode includes a first main body portion and a first connection portion, the second anode includes a second main body portion and a second connection portion, the spacer is located between the first and second main body portions in adjacent anode group rows. An overlapping area between the spacer and the first via hole is less than 20% of an area of the first via hole.
