A display substrate and a display device are provided. The display substrate includes: a plurality of sub-pixels; a first electrode layer including a plurality of anode structures; and a pixel definition layer located on a side of the first electrode layer away from the base substrate and including a plurality of openings. For at least some sub-pixels, an orthographic projection of the opening of each sub-pixel falls into that of the anode structure of the sub-pixel on the base substrate, a figure of the orthographic projection of the opening of each sub-pixel has a different shape from a figure of the orthographic projection of the anode structure of the sub-pixel on the base substrate. The figure of the orthographic projection of the anode structure of each sub-pixel has more symmetry axis than the figure of the orthographic projection of the opening of the sub-pixel on the base substrate.
