WIPO Patent Application WO/2022/229780

A1

Provided is a light emitting device that is produced by a photolithography method and has high definition and good characteristics. The light emitting apparatus has first and second light emitting devices that are adjacent to each other. The first light emitting device has a first EL layer A and a second EL layer. The second light emitting device has a first EL layer B and the second EL layer. The first EL layer A and the first EL layer B are independent. The second EL layer is shared by the first and second light emitting devices. An end surface on the first EL layer B side of the first EL layer A and an end surface on the first EL layer A side of the first EL layer B face each other. The first EL layer A has a light emitting layer. The light emitting layer has a light emitting material and first and second organic compounds. The first organic compound has electron transporting properties. The second organic compound has hole transporting properties.
