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.
有机 EL 器件包括:阳极 (3);阴极 (4);以及位于阳极 (3) 和阴极 (4) 之间的有机薄膜层 (5)。有机薄膜层(5)包括:荧光发光层(51),包含荧光主控体和蓝色荧光掺杂剂;红色磷光发光层(52),包含红色磷光主控体和红色磷光掺杂剂;以及绿色磷光发光层(53),包含绿色磷光主控体和绿色磷光掺杂剂。红色磷光掺杂剂主要通过接收荧光宿主的三重态能量转移发光。绿色磷光掺杂剂主要通过绿色磷光发光层内的电荷重组发光。
