ORGANIC LIGHT EMITTING DEVICE

摘要

PURPOSE: An organic light emitting device is provided to improve driving-voltage characteristics since hole injection capability, hole transfer capability, and electron transport capability are improved. CONSTITUTION: An organic light emitting device comprises a first electrode, a light emitting layer and a second electrode. An organic layer is formed including a compound of chemical formula 1 and a phenylamine-based compound between the first electrode and the light emitting layer. The content of the compound of chemical formula 1 is 1-10 parts by weight based on 100 parts by weight of the total weight of the compound of chemical formula 1 and the phenylamine-based compound. The light-emitting layer comprises a phosphorescence dopant and further an electron transport layer.
