Patent ID: 8368063

Claim:
An organic semiconductor device, comprising: a substrate; a gate electrode above the substrate; a gate insulation film over the gate electrode; a first electrode above the gate insulation film, the first electrode being one of a source electrode and a drain electrode; a second electrode above the gate insulation film, the second electrode being annular and surrounding the first electrode, the second electrode being an other of the source electrode and the drain electrode; an organic semiconductor layer above the gate insulation film and over the first electrode, the second electrode surrounding the organic semiconductor layer and defining an outer periphery of the organic semiconductor layer; a conductive guiding member above the gate insulation film, the conductive guiding member being annular and surrounding the second electrode; and a protective film above the gate insulation film and over the organic semiconductor layer and the second electrode, the conductive guiding member surrounding the protective film and defining an outer periphery of the protective film.
