Abstract: A method for producing a color filter, by which a highly flat coloring layer can be efficiently formed even in the case of using an inkjet method, comprising steps of: an inkjet step of applying a coloring layer-forming coating liquid by an inkjet method at an opening of a black matrix substrate which includes a transparent substrate and a light shielding part that is formed on the transparent substrate and has the opening, and thereby forming a pre-drying coloring layer; a reduced-pressure drying treatment step of subjecting the pre-drying coloring layer to a reduced-pressure drying treatment, and forming a color filter substrate having a post-drying coloring layer formed thereon; and a baking treatment step of subjecting the color filter substrate to a prebaking treatment and subsequently to a post-baking treatment, and obtaining a color filter having a coloring layer formed thereon, wherein in the reduced-pressure drying treatment, the pre-drying coloring layer is subjected to the reduced-pressure drying t

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.
