Abstract
(EN)
The present disclosure provides a display substrate, a display device and a manufacturing method for the display substrate, which belong to the technical field of displays, and can at least partially solve the problem of color mixing in existing organic light emitting diode type display substrates. The display substrate of the present disclosure comprises a base, a pixel defining layer arranged on the base, and a plurality of organic light emitting diodes arranged in an array, wherein a plurality of pixel receiving holes are formed in the pixel defining layer, the organic light emitting diodes are in one-to-one correspondence with the pixel receiving holes, and located in the corresponding pixel receiving holes; a plurality of supporting structures in one-to-one correspondence with the pixel receiving holes are formed on the side, facing away from the base, of the pixel defining layer, and orthographic projections of the supporting structures on the pixel defining layer surround the corresponding pixel receiving holes.
