摘要： Disclosed is an organic EL element which requires a low electric power and can exhibit high reliability under high temperature environments. Specifically disclosed is an organic EL element produced by forming, between an anode (2) and a cathode (4) by lamination, an organic layer (3) which comprises at least a light-emitting layer (3b). The light-emitting layer (3b) is composed of at least a host material that has a ratio of the electron mobility (μeEM) to the hole mobility (μhEM) (i.e., a μeEM/μhEM ratio) of 0.6 to 10 inclusive, a light-emitting dopant that can emit light, and a hole-transporting dopant. The light-emitting layer (3b) is characterized in that the ratio of the hole mobility (μhHT) of the hole-transporting dopant to the electron mobility (μeEM) of the host material (i.e., a μhHT/μeEM ratio) is 0.1 to 10 inclusive.
