Abstract: An OLED display substrate includes a base substrate with a display region arranged thereon. First, second and third sub-pixels are arranged in the display region. A first electrode layer, a pixel defining layer, a second electrode layer, and organic functional layers are arranged in the display region. The organic functional layers include first, second and third light-emitting layers. The first light-emitting layer covers the display region and is an integral structure. The second and third light-emitting layers are arranged on a side of the first light-emitting layer towards the second electrode layer. An orthographic projection of each sub light-emitting layer of the second and third light-emitting layers on the base substrate completely covers an orthographic projection of an opening of the pixel defining layer on the base substrate, and does not overlap with orthographic projections of other openings of the pixel defining layer on the base substrate.
