Patent ID: 8134148

Claim:
A light-emitting device comprising: a light-emitting element comprising: an anode and a cathode; and a light-emitting layer interposed between the anode and the cathode, wherein the light-emitting layer comprises an organic compound containing a diarylamino group and a double bond, the organic compound being represented by the structure: wherein Ar 1 and Ar 2 in the diarylamino group each represent an aryl group having 6 to 25 carbon atoms, wherein A 11 is selected from wherein Ar 21 represents an aryl group having 6 to 25 carbon atoms, wherein R 31 represents any one of a hydrogen atom, an alkyl group having 1 to 4 carbon atoms, and an aryl group having 6 to 25 carbon atoms, wherein R 32 represents any one of an alkyl group having 1 to 4 carbon atoms and an aryl group having 6 to 25 carbon atoms, wherein Ar 31 represents an aryl group having 6 to 25 carbon atoms, wherein β represents an arylene group having 6 to 25 carbon atoms, and wherein R 41 and R 42 each represent any one of a hydrogen atom, an alkyl group having 1 to 4 carbon atoms, and an aryl group having 6 to 25 carbon atoms.
