摘要： A display substrate and a display apparatus. The display substrate comprises a base substrate (10), a plurality of sub-pixels (100), a pixel defining layer (200) and a plurality of spacers (300). Each sub-pixel (100) comprises a light-emitting region (101); the pixel defining layer (200) comprises a plurality of openings (210) so as to define the light-emitting regions (101) of the plurality of sub-pixels (100); and the spacers (300) are located on the side of the pixel defining layer (200) that is away from the base substrate (10), and are distributed at gaps between adjacent openings (210). The shape of at least one opening (210) is in the shape of a polygon (400) with at least one vertex angle (401) cut off; a corner portion of the opening (210) comprises a first corner portion (1011), and the corner portion is a corner portion formed after the polygon (400) has a vertex angle (401) sandwiched by two edges cut off; at least one spacer (300) is arranged at a gap between the corner portion and the opening (210) adjacent to the corner portion; and a connection line between the geometric center of the opening (210) where the corner portion is located and the geometric center of the adjacent opening (210) passes through the corner portion and the spacer (300). According to the embodiments of the present disclosure, the spacers are arranged at the gaps of the openings of the pixel defining layers corresponding to the corner portions, thereby facilitating the improvement of the process yield or the improvement of the support effect of the spacers.
