    摘要: Provided are an OLED display substrate (100) and an OLED display device, in the field of display device. The OLED display substrate (100) includes a plurality of pixels, and each of the pixels includes two sub-pixels. The two sub-pixels include a first sub-pixel (210) and a second sub-pixel (220). The first sub-pixel (210) includes a first light-emitting unit (211) and a second light-emitting unit (212) that are stacked; the second sub-pixel (220) includes a third light-emitting unit (213); and the first light-emitting unit (211), the second light-emitting unit (212) and the third light-emitting unit (213) are configured to emit lights with different colors. Under the same resolution, the aperture ratio of the OLED display substrate (100) may be increased. Alternatively, under the same size of sub-pixels, the resolution of the OLED display substrate (100) may be increased. Therefore, the brightness uniformity and display effect of the OLED display panel are improved.
