摘要： Provided in the present disclosure are a light-emitting substrate and a display apparatus. The light-emitting substrate includes: a driving backplane; a plurality of light-emitting chips, arranged on the driving backplane in an array, where the light-emitting chip includes a buffer layer, an N-type semiconductor layer, a multi-quantum well layer, and a P-type semiconductor layer sequentially arranged on the driving backplane in a stacked manner; and a grating structure, on a side of the plurality of light-emitting chips facing away from the driving backplane, where the grating structure has a plurality of regions, and the regions are configured to transmit light of different wavelength bands.
