A semiconductor composition that can be used to form a semiconductor layer exhibiting high field effect mobility, air stability, and good solubility. The semiconductor composition includes a diketopyrrolopyrrole-thiophene copolymer and a non-aromatic halogenated hydrocarbon solvent containing at least 2 carbon atoms and at least 3 halogen atoms. Preferably, the non-aromatic halogenated hydrocarbon solvent contains at least 2 carbon atoms and at least 3 halogen atoms. [Selection figure] None |
