## Claims

### Claim 1

A hole transport material for an organic electroluminescence device, the hole transport material being represented by the following Formula 1:
wherein, in Formula 1, X is an aryl group or a heteroaryl group having 6 to 18 carbon atoms, Y is an aromatic ring, a condensed ring, or a heterocycle containing nitrogen having 6 to 18 carbon atoms, Z is O or S, Ar is an aryl group or a heteroaryl group having 6 to 18 carbon atoms, R is an aryl group or a heteroaryl group having 6 to 10 carbon atoms, or an alkyl group having 1 to 12 carbon atoms, and a is an integer of 0 to 3.

### Claim 2 (depends on 1)

An organic electroluminescence device comprising a hole transport layer that includes the hole transport material as claimed in claim 1.

### Claim 3

A hole transport material for an organic electroluminescence device, the hole transport material being represented by the following Formula 1:
wherein, in Formula 1, Y is an aromatic ring, a condensed ring, or a heterocycle containing nitrogen having 6 to 18 carbon atoms, Z is O or S, Ar is an aryl group or a heteroaryl group having 6 to 18 carbon atoms, R is an aryl group or a heteroaryl group having 6 to 10 carbon atoms, or an alkyl group having 1 to 12 carbon atoms, a is an integer of 0 to 3, and X in is selected from monovalent groups represented by (2) to (15) (* represents a bonding site) of following Formula 2,

### Claim 4 (depends on 3)

An organic electroluminescence device comprising a hole transport layer that includes the hole transport material as claimed in claim 3.
