An organic semiconductor film that can be used for an electron device, for example, particularly can be used for organic TFTs so as to allow the TFTs to have advanced performance, is provided and a manufacturing method therefor is provided. For instance, the organic semiconductor film contains the organic conductive high polymer compound such as polythiophene represented by the below formula (I). The organic semiconductor film is formed by forming a solution in a thin film form, the solution showing two or more spectral peaks (spectral state B) in a wavelength region of 300 to 800 nm by measurement using a visible and ultraviolet absorption spectral method; and drying the solution formed in the thin film form. Alternatively, the organic semiconductor film can be formed by the method in which the organic conductive high polymer compound has a molecular weight distribution range Mw/Mn from 1.00 to 1.85, obtained by dividing a weight-average molecular weight Mw by a number-average molecular weight Mn. With these methods, principal chains of the organic conductive high polymer compound molecules are arranged substantially in parallel, thus enhancing carrier mobility. |
