Abstract
The present disclosure provides a display substrate and a display device. The display substrate includes a first electrode structure, an organic light-emitting layer and a second electrode structure orderly arranged on a base substrate. The display substrate further includes a filter film located on a light-emitting side of the display substrate. A light absorption rate of a first electrode structure or a second electrode structure is greater than a first threshold.
