Abstract
A method for manufacturing a uniform organic semiconductor thin film consisting of single organic molecule with extremely few pinholes and of which both quality and thickness are uniform when the organic semiconductor thin film is manufactured by printing process. The uniform organic semiconductor thin film is manufactured by steps of: preparing a first ink obtained by dissolving a high concentration of the organic semiconductor in an organic solvent with high affinity for the organic semiconductor, and a second ink consisting of an organic solvent having a low affinity for the organic semiconductor; mixing the first and second inks on a substrate by simultaneously or alternately discharging the first and second inks from each ink head.
