| abstract |
A light-emitting element having excellent luminance life is provided. The device includes an anode, a cathode, and a first organic layer and a second organic layer provided between the anode and the cathode, wherein the first organic layer is represented by the formula (C-1). Wherein the second organic layer comprises a structural unit having a group obtained by removing one or more hydrogen atoms from a specific phosphorescent iridium complex; and A light-emitting element which is a layer A containing at least one kind of a crosslinked body or a layer B containing a specific phosphorescent iridium complex and a crosslinked body of a crosslinking material. [Wherein, R 1C to R 4C represent an aromatic hydrocarbon ring or the like. R C represents a carbon atom or the like. ] [Selection diagram] None |
