Abstract:
1. An organic light-emitting diode, comprising: a substrate; a first electrode on the substrate; a second electrode facing the first electrode; an emission layer interposed between the first electrode and the second electrode; a hole transportation region between the first electrode and the emission layer; and an electron transportation region interposed between the emission layer and the second electrode, wherein the hole transportation region includes a first compound represented by Formula 1 below, and at least one of the hole transportation region and the emission layer includes a second compound represented by Formula 100 below: in Formula 1, Ar xa and xb are each independently an integer of 0 to 5; R R 102 to R 108 and R 111 to R 119 are each independently selected from a hydrogen atom, a deuterium atom, a halogen atom, a hydroxyl group, a cyano group, a nitro group, an amino group, an amidino group, hydrazine, hydrazone, a carboxyl group or a salt thereof, a sulfonic acid or a salt thereof, a phosphoric acid or a salt thereof, a substituted or unsubstituted C 1 -C 60 alkyl group, a substituted or unsubstituted C 2 -C 60 alkenyl group, a substituted or unsubstituted C 2 -C 60 alkynyl group, a substituted or unsubstituted C 1 -C 60 alkoxy group, a substituted or unsubstituted C 3 -C 10 cycloalkyl group, a substituted or unsubstituted C 2 -C 10 heterocycloalkyl group, a substituted or unsubstituted C 3 -C 10 cycloalkenyl group, a substituted or unsubstituted C 2 -C 10 heterocycloalkenyl group, a substituted or unsubstituted C 6 -C 60 aryl group, a substituted or unsubstituted C 6 -C 60 aryloxy group, a substituted or unsubstituted C 6 -C 60 arylthyo group, a substituted or unsubstituted C 2 -C 60 heteroaryl group, —N(Q 1 )(Q 2 ), and —Si(Q 3 )(Q 4 )(Q 5 ) (wherein, Q 1 to Q 5 are each independently a C 1 -C 60 alkyl group, a C 1 -C 60 alkoxy group, a C 6 -C 60 aryl group, or a C 2 -C 60 heteroaryl group); and in Formula 100, i) R ii) R Ar Ar p and q are each independently an integer of 0 to 5.
