Abstract
A method for manufacturing a light-emitting element includes a) forming an intermediate layer containing a first resin on a charge transport layer, b) forming a light-emitting layer containing a second resin, a second photosensitive material, and a first luminescent material on the intermediate layer, c) exposing the intermediate layer and the light-emitting layer in a predetermined pattern to obtain an exposed intermediate layer and an exposed light-emitting layer, respectively, and d) developing the exposed intermediate layer and the exposed light-emitting layer with a developing solution. A solubility of a second portion of the exposed intermediate layer dissolved in the developing solution and a solubility of a first portion of the exposed light-emitting layer dissolved in the developing solution are different from each other.
