Abstract:
An organic EL device includes: an anode for injecting holes; a phosphorescent-emitting layer; a fluorescent-emitting layer; and a cathode for injecting electrons. The phosphorescent-emitting layer contains a phosphorescent host and a phosphorescent dopant for phosphorescent emission. The fluorescent-emitting layer contains a fluorescent host and a fluorescent dopant for fluorescent emission. The fluorescent host is at least one of an asymmetric anthracene derivative represented by a formula (1) below and a pyrene derivative represented by a formula (2) below.
