It is understood that the first electrode layer 20 in the present embodiment may have a grid shape, and the second electrode layer 30 may have a grid shape.
In this embodiment, an initial electrode layer 50 (fig. 4) may be deposited on the surface of the substrate layer 10, the initial electrode layer 50 may include a first organic layer a, a metal layer C, and a second organic layer B that are sequentially stacked, and the initial electrode layer 50 may be exposed and developed to form the first electrode layer 20, or the first organic layer a, the metal layer C, and the second organic layer B may be directly and sequentially formed on the surface of the substrate layer 10, and then the first organic layer a, the metal layer C, and the second organic layer B may be exposed and developed to form the first electrode layer 20 (fig. 5).
