The present invention relates to a novel heterocyclic compound and an organic light emitting device including the same.
Background
In general, the organic light emitting phenomenon refers to a phenomenon of converting electric energy into light energy using an organic substance. An organic light emitting device using an organic light emitting phenomenon has a wide viewing angle, excellent contrast, a fast response time, and excellent luminance, driving voltage, and response speed characteristics, and thus a great deal of research is being conducted.
An organic light emitting device generally has a structure including an anode and a cathode, and an organic layer between the anode and the cathode. In order to improve the efficiency and stability of the organic light emitting device, the organic layer is often formed of a multilayer structure formed of different materials, and may be formed of, for example, a hole injection layer, a hole transport layer, a light emitting layer, an electron transport layer, an electron injection layer, or the like. In the structure of such an organic light emitting device, if a voltage is applied between both electrodes, holes are injected from the anode into the organic layer, electrons are injected from the cathode into the organic layer, and when the injected holes and electrons meet, excitons (exiton) are formed, which emit light when they transition to the ground state again.
For organic materials used for the organic light emitting devices as described above, development of new materials is continuously demanded.
