Abstract:
A problem to be solved of the present invention is to provide a liquid composition for an organic semiconductor device having good coating property, wherein the lifetime of the function of an organic semiconductor device is prolonged when an organic layer is formed from the liquid composition for an organic semiconductor device, and a process for producing the liquid composition. A mean for solving the problem is a process for producing a liquid composition for an organic semiconductor device comprising a step of dissolving an organic compound which is solid at 1 atm and 25° C. in an organic solvent which is liquid at 1 atm and 25° C. and has a halogen compound concentration of not more than 100 ppm by weight.
