Abstract
To provide an organic electroluminescence device that can suppress rise in the driving voltage at the time of constant-current energization and degradation in brightness at the time of energization, and thus excels in its driving lifetime, the organic electroluminescence device comprises: a substrate; an anode and a cathode overlying the substrate; and a plurality of organic layers disposed between the anode and the cathode, and the plurality of organic layers comprise at least: a first layer formed by means of polymerization of a polymerizable compound; and a second layer disposed adjacently to the first layer and containing a polymerization initiator.
