The present invention provides an organic semiconductor solution having an organic semiconductor film having an allowable semiconductor property by improving film formability by containing a polymer of a substantial amount. The organic semiconductor solution of the present invention contains an organic solvent, a polymer dissolved in an organic solvent, and an organic semiconductor precursor, and the ratio of the polymer is 3% by mass or more based on the total of the polymer and the organic semiconductor precursor. The semiconductor precursor has a structure in which a diene type olefin which is detachable via a double bond thereof is added to a benzene ring of the organic semiconductor compound of the above formula (I): □ (A1 to A8 and E1 to E4 are each independently A hydrogen atom, a halogen atom, an alkyl group having 1 to 20 carbon atoms, or the like is selected, and Y is sulfur or selenium). |
