ABSTRACT:
The device according to the invention is a device having organic thin films containing a light-emitting layer between an anode and a cathode that emits light by application of electric energy, characterized in that the light-emitting device contains at least a compound having the basic skeleton represented by the following General Formula (1) or (2). Use of the condensed polycyclic compound according to the invention allows production of high-brightness, high-efficiency light-emitting device superior in color purity.
