Abstract: Detection electrode wirings formed by an ITO film have a high resistance and the detection capability thereof is degraded with the increase of the size and/or resolution. A manufacturing method of a display device includes: (a) arranging liquid crystal between an array substrate and a counter substrate; (b) forming a metal layer and a low-reflection layer on the counter substrate after the step (a); (c) applying an overcoat film onto the metal layer and the low-reflection layer; and (d) curing the overcoat film to form a protection layer. The step (d) cures the overcoat film with light and heat.
