(57) [Summary] [Purpose] When a photosensitive resin composition solution is applied to a support film, there is no uneven color, vertical stripes, horizontal stripes, etc. Provide the law. [Structure] A photosensitive resin composition solution in which a photosensitive resin composition is dissolved in an organic solvent is applied on a film support and dried to form an ultrathin film photosensitive resin composition having a film thickness of 0.5 to 5 μm. In the method for producing an ultra-thin photosensitive film that forms a layer, A method for producing an ultrathin photosensitive film, characterized in that a contact angle when the photosensitive resin composition solution is applied onto a film support is 12 to 20 degrees. |
