Patent ID: 8629429

Claim:
An organic device comprising: a first gate electrode; a first gate insulating film over the first gate electrode; a first organic layer over the first gate insulating film; an electrode over the first organic layer; a second organic layer over the electrode; a second gate insulating film over the second organic layer; and a second gate electrode over the second gate insulating film, wherein the electrode comprises a metal having a work function of 4.2 eV or less, a metal having a work function of more than 4.2 eV, and an organic compound, wherein the metal having a work function of 4.2 eV or less and the organic compound are mixed in the electrode on a side in contact with the first organic layer, wherein the metal having a work function of more than 4.2 eV and the organic compound are mixed in the electrode on a side in contact with the second organic layer, and wherein a molar ratio of the metal having a work function of 4.2 eV or less and the metal having a work function of more than 4.2 eV is 1/10 or more and 10/1 or less.
