ORGANIC LIGHT EMITTING DEVICE

摘要

PURPOSE: An organic light emitting device is provided to have an improved lifetime by suppressing the degradation of the organic light emitting layer by adding phosphorescent dopant. CONSTITUTION: An anode(12) is formed on a substrate(11). An intermediate layer(13) is formed on the anode. A light emitting layer(14) is formed on the intermediate layer. The light emitting layer includes fluorescent polymer materials and phosphorescent material dopant. A cathode(15) is formed on the light emitting layer.
