Patent ID: 8368057

Claim:
An organic thin film transistor, comprising: a gate electrode; a gate insulating film disposed on said gate electrode; a source electrode disposed on said gate insulating film; a drain electrode disposed on said gate insulating film, said gate insulating film, said drain electrode, and said source electrode cooperatively defining a channel portion, said drain electrode and said source electrode being separated from each other by said channel portion; and an organic active layer that is disposed on said gate insulating film in said channel portion and that is in contact with said source electrode and said drain electrode, wherein said organic active layer includes an organic semiconductor compound represented by the following formula (A): wherein m is 1 or 2; n is 1 or 2, R 1 is a carbonyl group or and R 2 is a carbonyl group or R 3 and R 4 being independently H or —C≡C—Si(CH(CH 3 ) 2 ) 3 ; wherein R 5 , R 6 , R 7 , and R 8 are independently hydrogen, a carboxyl group, a halogen-containing group, an ester group, a nitro group, or an aldehyde group; or R 5 and R 6 together form —(C═O)—O—(C═O)— or R 7 and R 8 being independently hydrogen, a carboxyl group, a halogen-containing group, an ester group, a nitro group, or an aldehyde group, R 9 being an aldehyde group, an ester group, or a nitro group; or R 7 and R 8 together form —(C═O)—O—(C═O)— or R 5 and R 6 being independently hydrogen, a carboxyl group, a halogen-containing group, an ester group, a nitro group, or an aldehyde group, R 10 being an aldehyde group, an ester group, or a nitro group.
