PRODUCTION METHOD FOR COLOR FILTER

Abstract

A main object of the present invention is to provide a production method for a color filter capable of producing a color filter with little white spots by the ink jet method, without limitation of the application derived from the presence of the moisture. To achieve the object, the invention provides a production method for a color filter using a substrate for a color filter having a base material, and a light shielding part formed on the base material and having a plurality of opening parts, comprising: a lyophilic process step of processing each of a base material surface in the opening parts to be lyophilic by contacting each of the base material surface in the opening parts with lyophilic process solution which contains an organic solvent having a hydroxyl group and no water; and a colored layer forming step of forming a colored layer on each of the base material surface in the opening parts processed to be lyophilic in the lyophilic process step by an ink jet method.
