摘要 |
<p>Disclosed is an organic electroluminescent device having high luminance and long-term stability under high temperature, high humidity conditions. This organic electroluminescent device is suppressed in voltage increase and generation of dark spots when driven at a constant current. Also disclosed are a display and an illuminating device using such an organic electroluminescent device. The organic electroluminescent device is characterized in that at least one of organic layers constituting the device is a light-emitting layer containing a host compound and a phosphorescent compound represented by the general formula (1) below, and the at least one organic layer has a film surface density of 1.10-1.25 g/cm<SUP>3</SUP>.</p> |
