Abstract:
A high-efficiency, high-durability organic electroluminescent device, particularly a phosphorescent organic electroluminescent device is provided by using an organic compound of excellent characteristics that exhibits excellent hole-injecting/transporting performance and has high triplet exciton confining capability with an electron blocking ability, and that has high stability in the thin-film state and high luminous efficiency.The organic electroluminescent device includes a pair of electrodes, and a plurality of organic layers sandwiched between the pair of electrodes and including a phosphorescent light-emitting material-containing light emitting layer and a hole transport layer, wherein a compound of the following general formula (1) having a carbazole ring structure is used as a constituent material of the hole transport layer.
