Abstract:
An organic electroluminescent device of which emission life may be improved. The organic electroluminescent device includes an anode, an emission layer, and an anode-side hole transport layer provided between the anode and the emission layer and including an anode-side hole transport material. An electron accepting material is doped in the anode-side hole transport layer. An intermediate hole transport material layer is provided between the anode-side hole transport layer and the emission layer and includes an intermediate hole transport material, and an emission layer-side hole transport layer is provided between the intermediate hole transport material layer and the emission layer and adjacent to the emission layer. The emission layer-side hole transport layer includes an emission layer-side hole transport material represented by the following Formula 1.

Claim (Index 1):
An organic electroluminescent (EL) device, comprising:\n an anode; an emission layer; and an hole transport layer between the anode and the emission layer; wherein the hole transport layer comprises a hole transport material represented by Formula 1: wherein in Formula 1, Y is O or S; R 1  to R 6  are each independently hydrogen, deuterium, a halogen atom, a substituted or unsubstituted alkyl group having 1 to 15 carbon atoms, a substituted or unsubstituted silyl group, a substituted or unsubstituted aryl group having 6 to 30 carbon atoms for forming a ring, a substituted or unsubstituted heteroaryl group having 1 to 30 carbon atoms for forming a ring, or a substituted or unsubstituted aryl group or heteroaryl group formed via condensation of optional adjacent substituents; Ar 1  and Ar 2  are each independently a substituted or unsubstituted aryl group having 6 to 30 carbon atoms for forming a ring, and each of Ar 1  and Ar 2  is not a heteroaryl-containing group; L 1  to L 3  are each independently a direct linkage, a substituted or unsubstituted alkylene group having 1 to 15 carbon atoms, a substituted or unsubstituted aralkylene group having 7 to 30 carbon atoms, a substituted or unsubstituted arylene group having 6 to 30 carbon atoms for forming a ring, a substituted or unsubstituted heteroarylene group having 1 to 30 carbon atoms for forming a ring, or a substituted or unsubstituted divalent silyl group; m is an integer from 0 to 3, and n is an integer from 0 to 4.
