Original Abstract Submitted
A light-emitting substrate includes a substrate, a plurality of sub-pixels, a first light extraction layer and a second light extraction layer. Each sub-pixel includes a light-emitting element and a light conversion pattern disposed on a light-exit side of the light-emitting element. The plurality of sub-pixels include at least one first sub-pixel. The first light extraction layer is disposed on a side of the first sub-pixel away from the light-emitting element, and at least located in a region where the at least one first sub-pixel is located. The first light extraction layer includes first transparent substrate(s) and optically active substances added in each first transparent substrate. The second light extraction layer is disposed on a side of the first light extraction layer away from the light-emitting element. A refractive index of the second light extraction layer is smaller than a refractive index of the first light extraction layer.
