An organic EL display device includes in order from a substrate side: a metal layer; an insulating layer formed on the metal layer; a first electrode layer formed on the insulating layer; an organic layer formed on the first electrode layer; and a second electrode layer formed on the organic layer. The metal layer is for use as a reflective layer configured to reflect, on a surface of the metal layer, light generated from the organic layer by applying a voltage between the first electrode layer and the second electrode layer.
