2. A compound of any one of the following Chemical Formulae 2 to 4 and 7:, wherein, in Chemical Formulae 2 to 4 and 7:
X is O or S;
L1 is a direct bond; a phenylene group that is unsubstituted or substituted with a phenyl group, a cyano group, a pyridinyl group or a quinolinyl group; a biphenylene group that is unsubstituted or substituted with a cyano group or a phenyl group; an unsubstituted terphenylene group; an unsubstituted quaterphenylene group; a naphthylene group that is unsubstituted or substituted with a cyano group; an unsubstituted anthracenylene group; an unsubstituted phenanthrenylene group; an unsubstituted triphenylenylene group; an unsubstituted pyrenylene group; an unsubstituted 9,9-dimethylfluorenylene group; an unsubstituted 9,9-diphenylfluorenylene group; an unsubstituted 9,9-methylphenylfluorenylene group; or an unsubstituted spiro[cyclopentane-1,9′-fluorenylene] group;
L2 is a direct bond or a substituted or unsubstituted arylene group;
X1 is N or CR1, X2 is N or CR2, X3 is N or CR3, and at least two of X1 to X3 are N;
R1 to R3 are the same as or different from each other, and each independently is hydrogen, deuterium, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted heteroaryl group;
Ar1 and Ar2 are the same as or different from each other, and each independently is hydrogen, deuterium, a substituted or unsubstituted alkyl group, an aryl group having 6 to 24 carbon atoms that is unsubstituted or substituted with deuterium, a substituted or unsubstituted heteroaryl group having 2 to 20 carbon atoms and comprising one or more heteroatoms of O and S, or a substituted or unsubstituted heteroaryl group having 2 to 20 carbon atoms and comprising an N-comprising 6-membered ring; and
positions at which, , is substituted with, , are asymmetric.
