Description

[0001] HETERO-CYCLIC COMPOUND AND ORGANIC LIGHT EMITTING DEVICE COMPRISING THE SAME [0002]

This application claims the benefit of Korean Patent Application No. 10-2016-0083728 filed on July 01, 2016, the entire contents of which are incorporated herein by reference.

TECHNICAL FIELD The present invention relates to heterocyclic compounds and organic light emitting devices comprising the same.

The organic light emission phenomenon is one example in which current is converted into visible light by an internal process of a specific organic molecule. The principle of organic luminescence phenomenon is as follows. When an organic layer is positioned between an anode and a cathode, when a voltage is applied between the two electrodes, electrons and holes are injected into the organic layer from the cathode and the anode, respectively. Electrons and holes injected into the organic material layer recombine to form an exciton, and the exciton falls back to the ground state to emit light. An organic light emitting device using this principle may be generally composed of an organic material layer including a cathode, an anode, and an organic material layer disposed therebetween, for example, a hole injection layer, a hole transport layer, a light emitting layer, an electron transport layer, and an electron injection layer.

In order to improve the performance, life or efficiency of an organic light emitting device, development of materials for organic thin films is continuously required.
