ORGANIC ELECTROLUMINESCENCE DEVICE
摘要:
As an organic electroluminescence device that exhibits superior external quantum efficiency and durability during driving at high temperature, and small variation in chromaticity and small increase in voltage after high-temperature driving, it is provided that the organic electroluminescence device including on a substrate a pair of electrodes and at least one layer of an organic layer including a light emitting layer disposed between the electrodes, wherein the light emitting layer contains at least one specific blue phosphorescent iridium complex and any layer of the at least one layer of an organic layer contains at least one compound represented by Formula (1): wherein in Formula (1), each of R1 to R5 independently represents a specific group or atom, n1 represents an integer of 0 to 5, and each of n2 to n5 independently represents an integer of 0 to 4.
