Abstract:
1. An organic transistor including a gate electrode (b), a gate insulating film (c), and an organic semiconductor layer (d) which contacts the gate insulating film, is formed by printing or coating, and has a channel formation area, and source/drain electrodes (e), which are formed on (a) a substrate, wherein the organic semiconductor layer contains a fluorinated (meth) acrylic polymer, which is made using a fluorinated (meth)acrylate as a raw material; and the fluorinated (meth)acrylate is denoted by (wherein R 1 denotes H, CH 3 , Cl, F, or CN, X denotes a bivalent bonding group, specifically, —(CH 2 ) n , —CH 2 CH(OH)(CH 2 ) n —, —(CH 2 ) n N(R 2 )SO 2 —, —(CH 2 ) n N(R 2 )CO— (wherein n is an integer in a range of 1 to 10, R 2 denotes H or an alkyl group having 1 to 18 carbon atoms), —CH(CH 3 )—, —CH(CH 2 CH 3 )—, —C(CH 3 ) 2 —, —CH(CF 3 )—, —C(CF 3 ) 2 —, and CH 2 CFH—, a denotes 0 or 1, and m denotes an integer of 1 to 20), wherein the organic semiconductor layer is made of an organic semiconductor material having crystallinity.
