Abstract: An object is to coat a target position on a substrate with a dense film. In order to achieve the object, while a substrate on which a base containing a coating material is formed is transported, an auxiliary agent is applied to the substrate, and then a main agent containing a coating material is applied to the substrate to react the main agent with the auxiliary agent, so that a portion on the substrate where the base is formed is coated with the coating material.

Abstract: A conductive film is installed on the display unit of the display device. The conductive film has a first conductive portion having a first wiring pattern in which a plurality of first openings of congruent convex pentagons constituted by thin metallic wires are arranged, and a second conductive portion disposed in the form of a layer to overlap at least a part of the first conductive portion with a gap therebetween. The second conductive portion has a second wiring pattern in which a plurality of openings constituted by thin metallic wires are provided. When viewed in a lamination direction in which the first conductive portion and the second conductive portion overlap each other, a coefficient of variation of an opening area is less than 52% in an opening group formed by the first wiring pattern of the first conductive portion and the second wiring pattern of the second conductive portion.
