This specification discloses Korean Patent Application No. 10-2014-0040818 filed with the Korean Patent Office on April 4, 2014, Korean Patent Application No. 10-2015-0017929 filed with the Korean Patent Office on February 5, 2015, and Claims the benefit of the filing date of Korean Patent Application No. 10-2015-0045586 filed with the Korean Intellectual Property Office on March 31, 2015, the contents of which are incorporated herein in their entirety.

The present specification relates to a heterocyclic compound and an organic light emitting device including the same.

In general, organic light emitting phenomenon refers to a phenomenon of converting electrical energy into light energy using an organic material. An organic light emitting device using an organic light emitting phenomenon usually has a structure including an anode, a cathode, and an organic material layer therebetween. The organic material layer is often made of a multi-layered structure composed of different materials to increase the efficiency and stability of the organic light emitting device, for example, it may be made of a hole injection layer, a hole transport layer, a light emitting layer, an electron transport layer, an electron injection layer. When the voltage is applied between the two electrodes in the structure of the organic light emitting device, holes are injected into the organic material layer at the anode and electrons are injected into the organic material layer, and excitons are formed when the injected holes and the electrons meet each other. When it falls back to the ground, it glows.

There is a continuing need for the development of new materials for such organic light emitting devices.

Described herein is a heterocyclic compound and an organic light emitting device comprising the same.
