LIGHT EMITTING DEVICE AND METHOD OF MANUFACTURING THE SAME

摘要

PURPOSE: A light emitting device and a manufacturing method thereof are provided to improve a drive voltage and an element lifetime by lowering energy barriers between organic layers. CONSTITUTION: A light emitting device including an organic light emitting element at least comprises an anode(101), a cathode(104), a first layer(102) including a first organic compound, a second layer(103) including a second organic compound which is different from the first organic compound, and a region(105) including the first organic compound and the second organic compound between the first layer and the second layer.
