Abstract:
1. An organic electroluminescence device comprising on a support substrate an anode and a cathode, and one or more organic layers between the anode and the cathode and at least one organic layer containing a reactive organic compound, wherein when an electric current is applied to device at a current density of from 0.01 mA/cm 2 to 10000 mA/cm 2 , a concentration of the reactive organic compound is reduced from a concentration before application of the electric current and when an emission luminance is reduced to 90% of an initial luminance by application of the electric current, a concentration (M90) of the reactive organic compound is within a range of 0.1 mol/cm 3 to 10 mol/m 3 .
