Abstract: This invention provides an OLED display substrate and a display device. The OLED display substrate includes a base substrate including a drive circuit layer; a first electrode layer including multiple independent first electrodes; and a pixel definition layer. A sub-pixel includes a first electrode and a light-emitting element. The sub-pixel includes a first-color sub-pixel, a second-color sub-pixel and a third-color sub-pixel. An orthographic projection of the first electrode of the first-color sub-pixel and the pixel definition layer onto the base substrate have a first overlap. An orthographic projection of the first electrode of the second-color sub-pixel and the pixel definition layer onto the base substrate have a second overlap. An orthographic projection of the first electrode of the third-color sub-pixel and the pixel definition layer onto the base substrate have a third overlap. The area of the first overlap is different from that of the second or third overlap.
