Claim 0:
1. A hetero-cyclic compound represented by the following Chemical Formula 1:, in Chemical Formula 1,
R1 and R2 are the same as or different from each other, and are each independently a substituted or unsubstituted alkyl group,
R3 to R5 are the same as or different from each other, and are each independently hydrogen; deuterium; a nitrile group; a nitro group; a hydroxy group; a carbonyl group; an ester group; an imide group; an amide group; a substituted or unsubstituted alkyl group; a substituted or unsubstituted cycloalkyl group; a substituted or unsubstituted alkoxy group; a substituted or unsubstituted aryloxy group; a substituted or unsubstituted alkylthioxy group; a substituted or unsubstituted arylthioxy group; a substituted or unsubstituted alkylsulfoxy group; a substituted or unsubstituted arylsulfoxy group; a substituted or unsubstituted alkenyl group; a substituted or unsubstituted silyl group; a substituted or unsubstituted boron group; a substituted or unsubstituted amine group; a substituted or unsubstituted arylphosphine group; a substituted or unsubstituted phosphine oxide group; a substituted or unsubstituted aryl group; or a substituted or unsubstituted heteroaryl group, and
L1 is a direct bond; a substituted or unsubstituted monocyclic or bicyclic arylene group; a substituted or unsubstituted phenanthrenylene group; a substituted or unsubstituted phenalenylene group; a substituted or unsubstituted fluorenylene group; a substituted or unsubstituted polycyclic arylene group, wherein the polycyclic arylene group refers to a cyclic arylene group contains a tetra—or more—cyclic arylene group; or a substituted or unsubstituted heteroarylene group,
Ar1 is a substituted or unsubstituted phosphine oxide group; or a substituted or unsubstituted dibenzofuranyl,
wherein the heteroaryl group in the heteroarylene group for L1 is a thiophene group, a furanyl group, a pyrrole group, a thiazolyl group, an oxazolyl group, an oxadiazolyl group, a triazolyl group, a quinoxalinyl group, a pyridopyrimidyl group, a pyridopyrazinyl group, a pyrazinopyrazinyl group, a carbazolyl group, a benzimidazolyl group, a benzocarbazolyl group, a benzothiophene group, a dibenzothiophene group, a benzofuranyl group, a phenanthrolinyl group, an isoxazolyl group, a thiadiazolyl group, a phenothiazinyl group, or a dibenzofuranyl group, and when the carbazolyl group is substituted, the carbazolyl group is N-substituted with an unsubstituted phenyl, an unsubstituted naphthyl, or an unsubstituted biphenyl group, provided when Ar1 is a substituted or unsubstituted dibenzofuranyl, the heteroaryl group in the heteroarylene group for L1 is not a carbazolyl group,
r3 is an integer from 1 to 4,
r4 is 1 or 2,
r5 is an integer from 1 to 3, and
when r3 to r5 each present in a plural number, a plurality of structures in the parenthesis is the same as or different from each other.
