Definitions
- the present specification relates to a heterocyclic compound and an organic light emitting device including the same.
- the electroluminescent device is a kind of self-luminous display device, and has an advantage of having a wide viewing angle, excellent contrast, and fast response speed.
- the organic light emitting element has a structure in which an organic thin film is arranged between two electrodes. When a voltage is applied to the organic light emitting device having such a structure, electrons and holes injected from two electrodes are combined in the organic thin film to form a pair, then disappear and emit light.
- the organic thin film may be composed of a single layer or multiple layers as necessary.
- the material of the organic thin film may have a light emitting function as needed.
- a compound which may itself constitute a light emitting layer may be used, or a compound that may serve as a host or a dopant of a host-dopant-based light emitting layer may be used.
- a compound capable of performing a role of hole injection, hole transport, electron blocking, hole blocking, electron transport, electron injection, or the like may be used.
- a heterocyclic compound represented by Formula 1 is provided.
- N-Het is a substituted or unsubstituted monocyclic or polycyclic heterocyclic group containing one or more N,

- the first electrode A second electrode provided to face the first electrode; And at least one organic material layer provided between the first electrode and the second electrode, wherein at least one of the organic material layers includes a heterocyclic compound represented by Chemical Formula 1.
- the compound described in this specification can be used as an organic material layer material of an organic light emitting element.
- the compound may serve as a hole injection material, a hole transport material, a light emitting material, an electron transport material, an electron injection material in the organic light emitting device.
- the compound can be used as the light emitting layer material of the organic light emitting device.
- the compound may be used alone as a light emitting material, or may be used as a host material of the light emitting layer.
- the N-containing ring is substituted at the carbon position of the dibenzofuran structure, and the carbazole structure is substituted for the benzene in which the N-containing ring is not substituted in the structure of the dibenzofuran structure, thereby providing a more electron stable structure. It is possible to improve the device life.
- 1 to 3 are diagrams schematically showing a laminated structure of an organic light emitting device according to an exemplary embodiment of the present application.
- substituted means that a hydrogen atom bonded to a carbon atom of the compound is replaced with another substituent, and the position to be substituted is not limited to a position where the hydrogen atom is substituted, that is, a position where a substituent can be substituted, if two or more substituted , Two or more substituents may be the same or different from each other.
