Abstract

A display substrate and a display apparatus. The display substrate comprises a base substrate, sub-pixels located on the base substrate, and a limiting structure. The sub-pixel comprises a light-emitting functional layer, which comprises a plurality of film layers; and the limiting structure is located between two adjacent sub-pixels of different colors and is configured to partition at least one layer of the light-emitting functional layer. The sub-pixels comprise sub-pixels of a first color, and the limiting structure adjacent to the sub-pixels of the first color in the limiting structure is a first limiting structure; a light-emitting area of the sub-pixels of the first color comprises a first edge extending in a first direction; the first limiting structure comprises two limiting end points, wherein in the first direction, at least one limiting end point protrudes relative to an edge end point of the first edge, or the first limiting structure has a curved shape; and the total length of the first limiting structure is greater than the size of the light-emitting area of the sub-pixels of the first color in at least one direction, so that the low-grayscale crosstalk problem caused by leakage current between the sub-pixels of the first color and sub-pixels of other colors is mitigated.
