The present invention provides a
display device and a method for manufacturing the
display device. A
metal layer is formed on a highly light-transmissive substrate; a
resist mask having an opening pattern is formed on the
metal layer; exposed portions of the
metal layer is etched away in this state to form openings; then the
resist mask is removed; and a surface of the metal layer and an inner side wall of each of the openings are oxidized to form a metal
oxide layer. Thus, a front surface and a rear surface of the aperture plate are caused to have different reflectances. The
oxide layer is formed at the same time as when the
resist mask is ashed to remove resist.
