Abstract
Provided in the present disclosure are a display substrate and a display apparatus. The display substrate comprises: a driving backplane; a light-emitting structure that is located on the driving backplane and that comprises a plurality of light-emitting devices; and a light-filtering structure located on the side of the light-emitting structure facing away from the driving backplane. The light-filtering structure comprises a plurality of light-filtering layers that correspond to at least a portion of the light-emitting devices, the light-emitting layers are provided with hollow spherical structures, and the light-filtering layers are hollow fan-shaped shapes in a cross section perpendicular to the driving backplane. The thicknesses of the light-filtering layers along the sphere center divergence direction of the hollow spherical structures are uniform. The problem of color cast caused by some light-filtering layers can be solved by means of designing the light-filtering layers into hollow spherical structures.
