Patent ID: 8692255

Claim:
A semiconductor element comprising: an organic semiconductor layer; an electrode disposed on said organic semiconductor layer so as to be in contact with said organic semiconductor layer; and a wiring layer formed separately from said electrode and electrically connected to said electrode, wherein the semiconductor element includes said organic semiconductor layer, a gate electrode, a pair of source-drain electrodes as said electrode, and said wiring layer, and is formed as a thin film transistor, a gate insulating film and a protective film, wherein said gate electrode, said gate insulating film, said organic semiconductor layer, said source-drain electrodes, said protective film, and said wiring layer are laminated on a substrate in order of said gate electrode, said gate insulating film, said organic semiconductor layer, said source-drain electrodes, said protective film, and said wiring layer, wherein said organic semiconductor layer has projection parts as regions overlapping said source-drain electrodes outside a region of formation of said protective film.
