Abstract
The disclosure relates to an OLED display substrate, a manufacturing method and a display apparatus. The OLED display substrate comprises a base substrate, and a plurality of light-emitting elements and a plurality of pixel defining layers formed on the base substrate, wherein a pixel defining layer is located between any two adjacent light-emitting elements of the plurality of light-emitting elements; and a surface of the pixel defining layer facing away from the base substrate comprises an accommodating portion, a bottom surface of the accommodating portion and the surface of the pixel defining layer facing away from the base substrate are located at different planes, and an orthographic projection of the accommodating portion on the base substrate does not overlap with an orthographic projection of the plurality of light-emitting elements on the base substrate. The method for manufacturing the OLED display substrate is configured to manufacture the above OLED display substrate.
