Abstract
Disclosed is an organic electroluminescent device having improved luminous efficiency. Specifically disclosed is an organic electroluminescent device (10) comprising at least an anode (11), an organic light-emitting layer (14) containing a phosphorescent material (14b) in a host material (14a), a hole-blocking layer (15), and a cathode (17) wherein the lowest excited triplet energy level of the material constituting the hole-blocking layer (15) is not lower than the lowest excited triplet energy level of the phosphorescent material (14b). It is preferable that a hole-injecting layer (12) and a hole-transporting layer (13) are arranged between the anode (11) and the organic light-emitting layer (14) while an electron-transporting layer (16) is arranged between the cathode (17) and the hole-blocking layer (15).
