摘要： An organic EL device includes: an anode; a cathode and an organic thin-film layer provided between the anode and the cathode. The organic thin-film layer includes: a fluorescent-emitting layer containing a fluorescent host and a fluorescent dopant; and a phosphorescent-emitting layer containing a first phosphorescent host and a first phosphorescent dopant. The first phosphorescent dopant emits light by receiving exited triplet energy transferred from the fluorescent host. The fluorescent host has a substituted or unsubstituted polycyclic fused aromatic skeleton and has an exited triplet energy gap of 2.10 eV to 3.00 eV.
