摘要： A light emitting device contains an anode, cathode, and two organic layers provided therebetween. One organic layer contains a phosphorescent compound, the second organic layer contains a block copolymer containing an end group, a block that binds to the end group and/or a block that does not bind to the end group, and a crosslinked product of the block copolymer. The non-terminal block contains a non-crosslinkable unit represented by the formula (X) and/or a non-crosslinkable unit represented by the formula (Z). At least one of XI>XII; ZI>ZII; XI+ZI>XII+ZII is satisfied when the total number of units having formula (X) and the total number of units having formula (Z) in the non-terminal block are XI and ZI, respectively, and the total number of units having formula (X) and the total number of units having formula (Z) in the terminal block are XII and ZII, respectively.
