According to one embodiment, a display device includes a stacked conductive layer. The stacked conductive layer includes a first conductive layer formed of material containing aluminum, and a second conductive layer provided on the first conductive layer, formed of material different from material of which the first conductive layer is formed, and having a higher visible-light absorptivity than that of the first conductive layer. The first conductive layer includes a side wall formed of an oxide film.
