Claim 7:
8. A manufacturing method of an organic light-emitting diode display substrate which has a plurality of pixel regions, comprising:
forming a pixel defining layer on a base substrate by a patterning process, and forming accommodation parts and guide parts in regions of the pixel defining layer corresponding to the pixel regions, wherein the accommodation parts penetrate the pixel defining layer, the guide parts are located on a periphery of corresponding accommodation parts and are formed by recessed areas which are formed at positions on a side of the pixel defining layer away from the base substrate, the recessed areas do not penetrate the pixel defining layer in a direction perpendicular to the base substrate, and
an orthographic projection of the guide part on the base substrate is directly coupled to an orthographic projection of the corresponding accommodation part on the base substrate.
