摘要： A method for manufacturing a light emitting device includes: providing a base layer and forming an electron transport layer including first and second transport regions. The forming of the electron transport layer includes: applying an electron transport composition including a metal oxide and a photoacid generator such that first and second preliminary transport regions are formed, and irradiating the first and second preliminary transport regions with light, and in the irradiating with the light, the amount of light per unit area irradiated on the first preliminary transport region is different from the amount of light per unit area irradiated on the second preliminary transport region.
