1. An organic electroluminescent compound represented by the following formula 1:, wherein
Y1 to Y14 each independently represent N or CR1, in which if a plurality of R1's is present, each R1 may be the same or different;
with the proviso that at least a pair of Y1 to Y14 wherein two of Y1 to Y14 are adjacent to each other are fused with the following formula 2 to form a ring:, Z represents NR2, O, S, CR3R4 or SiR5R6;
X1 to X4 each independently represent N or CR7, in which if a plurality of R7's is present, each R7 may be the same or different;
the dotted line represents a site fused with the adjacent two of Y1 to Y14 of formula 1;
R2 represents, wherein  represents the bonding site of La to the nitrogen of NR2;
La represents a single bond, a substituted or unsubstituted (C6-C30)arylene, a substituted or unsubstituted (3- to 30-membered)heteroarylene, or a substituted or unsubstituted (C3-C30)cycloalkylene;
Ar represents hydrogen, deuterium, a halogen, a cyano, a substituted or unsubstituted (C1-C30)alkyl, a substituted or unsubstituted (C6-C30)aryl, a substituted or unsubstituted (3- to 30-membered)heteroaryl, a substituted or unsubstituted (C3-C30)cycloalkyl, a substituted or unsubstituted (C1-C30)alkoxy, a substituted or unsubstituted tri(C1-C30)alkylsilyl, a substituted or unsubstituted di(C1-C30)alkyl(C6-C30)arylsilyl, a substituted or unsubstituted (C1-C30)alkyldi(C6-C30)arylsilyl, a substituted or unsubstituted tri(C6-C30)arylsilyl, a substituted or unsubstituted mono- or di-(C1-C30)alkylamino, a substituted or unsubstituted mono- or di-(C6-C30)arylamino, a substituted or unsubstituted (C6-C30)aryl(3- to 30-membered)heteroarylamino, or a substituted or unsubstituted (C1-C30)alkyl(C6-C30)arylamino;
R1 and R7 each independently represent hydrogen, deuterium, a halogen, a cyano, a substituted or unsubstituted (C1-C30)alkyl, a substituted or unsubstituted (C6-C30)aryl, a substituted or unsubstituted (3- to 30-membered)heteroaryl, a substituted or unsubstituted (C3-C30)cycloalkyl, a substituted or unsubstituted (C1-C30)alkoxy, a substituted or unsubstituted tri(C1-C30)alkylsilyl, a substituted or unsubstituted di(C1-C30)alkyl(C6-C30)arylsilyl, a substituted or unsubstituted (C1-C30)alkyldi(C6-C30)arylsilyl, a substituted or unsubstituted tri(C6-C30)arylsilyl, a substituted or unsubstituted mono- or di-(C1-C30)alkylamino, a substituted or unsubstituted mono- or di-(C6-C30)arylamino, a substituted or unsubstituted (C6-C30)aryl(3- to 30-membered)heteroarylamino, or a substituted or unsubstituted (C1-C30)alkyl(C6-C30)arylamino; or adjacent two R1's or adjacent two R7's may be linked to each other to form a ring;
R3 to R6 each independently represent hydrogen, deuterium, a halogen, a cyano, a substituted or unsubstituted (C1-C30)alkyl, a substituted or unsubstituted (C6-C30)aryl, or a substituted or unsubstituted (3- to 30-membered)heteroaryl; or R3 and R4, or R5 and R6 may be linked to each other to form a ring; and
a is an integer of 1 to 4, in which if a is 2 or more, each Ar may be the same or different.
