Abstract: The present disclosure provides an organic light-emitting display substrate and a display device. The display substrate includes a base substrate, a driving circuit layer on the base substrate and a light-emitting device on one side of the driving circuit layer away from the base substrate. The light-emitting device includes a first electrode layer including separated first electrode patterns. The display substrate further includes a reflective metal layer insulated from the first electrode layer. An orthographic projection of each reflective metal pattern onto the base substrate overlaps an orthographic projection of at least two first electrode patterns onto the base substrate, which can appropriately reduce a thickness of an anode layer due to the presence of the reflective metal layer, thereby reducing segment difference of the light-emitting layer near the anode, improving the uniformity of the light-emitting layer, and improving performance of the display panel.
