Patent ID: 7420204

Claim:
An organic electroluminescent transistor comprising: a source electrode and a drain electrode, which counter each other; an organic semiconductor layer provided between the source electrode and the drain electrode; and a plurality of gate electrodes arranged in the organic semiconductor layer at prescribed intervals, wherein the organic semiconductor layer is formed of an electroluminescent organic semiconductor material, wherein the electroluminescent organic semiconductor material comprises at least one of: (1) at least one kind of acene molecule material chosen from naphthalene, anthracene, tetracene, pentacene, hexacene, and derivatives thereof, (2) at least one kind of pigment chosen from a phthalocyanine containing compound, an azo containing compound, a perylene containing compound, and derivatives thereof, (3) at least one kind of low molecular compound chosen from hydrazone compound, triphenylmethane compound, diphenyl methane compound, stilbene compound, aryl vinyl compound, pyrazoline compound, triphenylamine compound, triarylamine compound, and derivatives thereof, and (4) at least one kind of high molecular compound chosen from poly N-vinyl carbazole, halogenated poly N-vinyl carbazole, poly vinyl pyrene, poly vinyl anthracene, pyrene formaldehyde resin, ethyl carbazole formaldehyde resin, and denaturations thereof.
