Abstract: A display substrate and a manufacturing method therefor. The display substrate comprises a base substrate (110), a driving circuit layer (120), a plurality of first electrodes (E1), and a pixel defining layer (PDL); the driving circuit layer (120) is provided on the base substrate (110) and comprises a plurality of pixel driving circuits (D) for a plurality of subpixels (SP) and a protective insulating layer (PLN) covering the plurality of pixel driving circuits (D); the plurality of first electrodes (E1) are provided on the side of the driving circuit layer (120) distant from the base substrate (110), and are respectively electrically connected to output terminals (T) of the plurality of pixel driving circuits (D) through a plurality of first via holes (PLN1) of the protective insulating layer (PLN); the pixel defining layer (PDL) is at least provided on the side of the plurality of first electrodes (E1) distant from the base substrate (110), and comprises a plurality of first openings (O1) respectively exposing the plurality of first electrodes (E1) and a plurality of second openings (O2) formed between adjacent subpixels (SP) among the plurality of subpixels (SP); and the pixel defining layer (PDL) has first partition structures (P1) at the plurality of first openings (O1) and has second partition structures (P2) at the plurality of second openings (O2). The display substrate has a high color gamut and a good display effect.
