Abstract
A light-emitting substrate includes a plurality of light-emitting devices including at least one first light-emitting device. Each light-emitting device includes a light-emitting pattern The first light-emitting device further includes a first material layer including a first material A material of a light-emitting pattern included in first light-emitting device includes a first light-emitting material. The first material is capable of generating a second material under light irradiation of a first wavelength band, and a solubility of the first material and a solubility of the first light-emitting material are each different from a solubility of the second material in a same solvent; or the first material is generated by a third material under light irradiation of a second wavelength band, and a solubility of the first material and a solubility of the first light-emitting material are each different from a solubility of the second material er the third material in a same solvent.
