Abstract
The present disclosure provides a display substrate and a display device. The display substrate comprises a base substrate and an anode, an organic light-emitting layer and a cathode formed on the base substrate sequentially, wherein the display substrate further comprises a plurality of functional patterns formed between the organic light-emitting layer and the anode, the plurality of functional patterns is divided into different types based on colors of a plurality of sub-pixels, and each type of the plurality of functional patterns is disposed in a region of the sub-pixel with a color corresponding to the type; the plurality of sub-pixels with different colors has different driving voltages, and a resistance value of each type of the plurality of the functional patterns in a direction perpendicular to the organic light-emitting layer is controlled to decrease as the driving voltage of the sub-pixel with the color corresponding to the type increases.
