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 100a and a second organic
layer 100b. 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 100a and the second
organic layer 100b.
