    Abstract: A display substrate, including a base substrate, a plurality of pixel units, and a pixel definition layer. The pixel unit includes a first sub-pixel, a second sub-pixel, a third sub-pixel, and a fourth sub-pixel. The fourth sub-pixel is a white sub-pixel, and any two of the first sub-pixel, the second sub-pixel, the third sub-pixel and the fourth sub-pixel display different colors. In at least one pixel unit, at least one of the first sub-pixel, the second sub-pixel and the third sub-pixel is located in a different row from the fourth sub-pixel. In at least one pixel unit, each of orthographic projections of a first opening of the first sub-pixel, a second opening of the second sub-pixel and a third opening of the third sub-pixel on the base substrate has an area less than that of a fourth opening of the fourth sub-pixel on the base substrate.
