1. A heterocyclic compound represented by the following Chemical Formula 2:

OG Complex Work Unit Chemistry
wherein, in Chemical Formula 2,
X is O; or S;
R1 to R8 are the same as or different from each other, and each independently selected from the group consisting of hydrogen; deuterium; a substituted or unsubstituted C6 to C40 aryl group; and a substituted or unsubstituted C2 to C40 heteroaryl group,
L1 and L2 are a C6 to C40 monocyclic arylene group; or a C10 to C40 polycyclic arylene group,
Z1 and Z2 are hydrogen; a substituted or unsubstituted C1 to C40 alkyl group; a substituted or unsubstituted C6 to C40 aryl group; a substituted or unsubstituted C2 to C40 heteroaryl group; or —P(═O)RR′,
R, and R′ are the same as or different from each other, and each independently a substituted or unsubstituted C6 to C40 aryl group;
m and p are an integer of 1 to 4, and when m is 2 or greater, the two or more L1s are the same as or different from each other, and when p is 2 or greater, the two or more L2s are the same as or different from each other; and
n and q are an integer of 1 to 6, and when n is 2 or greater, the two or more Z1s are the same as or different from each other, and when q is 2 or greater, the two or more Z2s are the same as or different from each other,
“substituted or unsubstituted” means being substituted with one or more substituents selected from the group consisting of C1 to C60 linear or branched alkyl; C6 to C60 monocyclic or polycyclic aryl; C2 to C60 monocyclic or polycyclic heteroaryl; and —P(═O)RR′; or being unsubstituted, or being substituted with a substituent linking two or more substituents selected from among the substituents above, or being unsubstituted.
