Kind Code:
A1
Abstract:
Provided in the present disclosure are a light-emitting substrate, a display panel, and a display apparatus. The light-emitting substrate comprises a plurality of light-emitting devices arranged in an array, and each light-emitting device comprises: a first electrode; a first light-emitting layer, which is located on the first electrode; a second light-emitting layer, which is located on the side of the first light-emitting layer that is away from the first electrode; a third light-emitting layer, which is located on the side of the second light-emitting layer that is away from the first electrode; a fourth light-emitting layer, which is located on the side of the third light-emitting layer that is away from the first electrode; and a second electrode, which is located on the side of the fourth light-emitting layer that is away from the first electrode. Three light-emitting layers among the first light-emitting layer, the second light-emitting layer, the third light-emitting layer and the fourth light-emitting layer emit light of a first wavelength, and the remaining light-emitting layer among the first light-emitting layer, the second light-emitting layer, the third light-emitting layer and the fourth light-emitting layer emits light of a second wavelength, wherein the first wavelength is less than the second wavelength.
