Patent ID: 8475938

Claim:
An organic electroluminescent element comprising plural organic compound layers including a light-emitting layer and a hole transport layer interposed between an anode and a cathode, a phosphorescent light-emitting compound contained in the light-emitting layer emitting light, wherein, the hole-transport layer contains two or more polymerizable compounds represented by Formula (1) which are different from each other or a polymer compound having a structural unit derived from two or more of the polymerizable compounds represented by Formula (1) which are different from each other, in Formula (1), L 1 represents a divalent bonding group containing an aromatic ring which is selected from the group consisting of a phenylene group, a biphenylene group, a fluorenylene group, a terphenylene group, a quarterphenylene group, a dibenzofuranylene group, a dibenzothiophenylene and a thiophene group, Ar 1 through Ar 4 represent an aromatic group, provided that at least two of Ar 1 through Ar 4 contain a polymerizable group as a substituent.
