To provide an electrode for an organic device which can be widely applied to organic devices by having both hole injection function and electron injection function. A carrier injection electrode layer 110 in which a metal for electron injection 112 (a metal having a work function of 4.2 eV or less) and a metal for hole injection 113 (a metal having a work function of more than 4.2 eV) are mixed with one kind of organic compound 111 is provided between a first organic layer 100 a and a second organic layer 100 b. Thus, carriers are injected into a carrier injection electrode layer 110 in the direction according to voltage application, and seemingly, current flows between an organic layer 100 and a metal electrode 101, or between the first organic layer 100 a and the second organic layer 100 b. |
