Abstract

The present specification provides a heterocyclic compound represented by Chemical Formula 1, an organic light emitting device comprising the same, a composition for an organic material layer of an organic light emitting device, and a method for manufacturing an organic light emitting device.

First claim

The invention claimed is:

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

wherein, in Chemical Formula 1-B,
X is O; or S;
R1 to R5 are hydrogen;
Ar1 and Ar2 are the same as or different from each other, and each independently a substituted or unsubstituted C1 to C60 alkyl group; a substituted or unsubstituted C6 to C60 aryl group; or a substituted or unsubstituted C2 to C60 heteroaryl group;
L1 is any one of the following structural formulae:

in the structural formulae,
X1 is O; or S;
L3 and L4 are the same as or different from each other, and each independently a direct bond; a substituted or unsubstituted C6 to C60 arylene group; or a substituted or unsubstituted C2 to C60 heteroarylene group;
Z3 and Z4 are the same as or different from each other, and each independently selected from the group consisting of hydrogen; deuterium; halogen; a cyano group; a substituted or unsubstituted C1 to C60 alkyl group; a substituted or unsubstituted C6 to C60 aryl group; a substituted or unsubstituted C2 to C60 heteroaryl group; and a substituted or unsubstituted amine group;
a and b are an integer of 0 to 5;
c and d are an integer of 1 to 6;
m is an integer of 1 to 4, and s is an integer of 0 to 3.

2 . The heterocyclic compound claim 1 , wherein Chemical Formula 1-B is represented by any one of the following Chemical Formulae 1-1-B to 1-4-B:

in Chemical Formulae 1-1-B to 1-4-B,
R1 to R5, X, Ar1, Ar2, L1, L3, L4, Z3, Z4, m, a, b, c, d and s have the same definitions as in Chemical Formula 1-B.

3 . The heterocyclic compound of claim 1 , wherein Chemical Formula 1-B is represented by any one of the following compounds:
