## Abstract

An organic light-emitting device includes an anode, a cathode, and an organic compound layer interposed between the anode and the cathode. The organic compound layer contains a heterocyclic compound having 4,10-Diazachrysene.

## Claims

### Claim 1

A heterocyclic compound that is used in organic light-emitting devices represented by general formula [1]:
(where R1 to R4 each independently represent a hydrogen atom, a substituted or unsubstituted aryl group, or a substituted or unsubstituted heterocyclic group;
and at least one of R1 to R4 represents a substituted or unsubstituted fused polycyclic aromatic group having four or more rings or a substituted or unsubstituted fused polycyclic heterocyclic group having four or more rings.

### Claim 2 (depends on 1)

The heterocyclic compound according to claim 1, wherein at least one of R1 to R4 represents a benzofluoranthenyl group.
