Abstract
A display wiring line provided on a resin substrate layer, a flattening film covering the display wiring line, and an organic EL element provided on the flattening film are provided. The display wiring line includes first to third conductive layers layered sequentially from the resin substrate layer side. In the display wiring line, the second conductive layer is formed with a width smaller than a width of each of the first conductive layer and the third conductive layer, and a portion of a perimeter edge surface corresponding to the second conductive layer includes a recessed portion, and a resin cover covering a perimeter edge surface of the second conductive layer is provided in the recessed portion in a portion of the display wiring line exposed from the flattening film.
