摘要： An organic EL device includes: an anode (3); a cathode (4); and an organic thin-film layer (5) provided between the anode (3) and the cathode (4). The organic thin-film layer (5) includes: a fluorescent-emitting layer (51) containing a fluorescent host and a blue fluorescent dopant; a red phosphorescent-emitting layer (52) containing a red phosphorescent host and a red phosphorescent dopant; and a green phosphorescent-emitting layer (53) containing a green phosphorescent host and a green phosphorescent dopant. The red phosphorescent dopant emits light mainly by receiving transfer of triplet energy from the fluorescent host. The green phosphorescent dopant emits light mainly by recombination of charges within the green phosphorescent-emitting layer.
