Abstract: The display device includes a light-emitting layer. The light-emitting layer includes light-emitting regions that have different predetermined luminescent colors and a non-light-emitting region that is different from the light-emitting regions and is formed in a region including an outer edge of the light-emitting layer. The non-light-emitting region includes a first outer edge region containing a first outer edge material different from a main luminescent material constituting the light-emitting region, at an outer edge of the light-emitting layer.
