1. An organic electroluminescent compound represented by the following formula 1:

OG Complex Work Unit Chemistry
wherein
Ar1 and Ar2 each independently represent a substituted with deuterium or unsubstituted (C6-C30)aryl, or a substituted with deuterium or unsubstituted (3- to 30-membered) heteroaryl, where if a plurality of Ar1 or Ar2 is present, each of Ar1 or each of Ar2 may be the same or different;
where if Ar1 and Ar2 each independently represent a substituted with deuterium or unsubstituted (C6-C30) aryl, or a substituted with deuterium or unsubstituted (3- to 30-membered) heteroaryl, Ar1 and Ar2 may be linked to each other via a single bond to form a ring(s);
L1 represents a single bond, a substituted with deuterium or unsubstituted (C6-C30) arylene, or a substituted with deuterium or unsubstituted (3- to 30-membered) heteroarylene, where if a plurality of L1 is present, each of L1 may be the same or different;
R1 and R2 each independently represent a substituted or unsubstituted (C1-C30) alkyl, a substituted or unsubstituted (C6 C30) aryl, or a substituted or unsubstituted (3- to 30-membered) heteroaryl;
R3 to R5 each independently represent hydrogen, deuterium, a halogen, a cyano, a substituted with deuterium or unsubstituted (C1-C30) alkyl, a substituted with deuterium or unsubstituted (C6-C30) aryl, a substituted with deuterium or unsubstituted (3- to 30-membered) heteroaryl, or a substituted with deuterium or unsubstituted (C3-C30) cycloalkyl, where if a plurality of R3 to R5 is present, each of R3, each of R4, and each of R5 may be the same or different; and
a represents an integer of 1 to 4, b represents 1 or 2, c represents an integer of 1 to 3, d represents 1 or 2, and c+d is 4, where if a, b, c, and d each independently are 2 or more, each of R3, each of R4, each of R5, and each of -L1-NAr1Ar2 may be the same or different.
