Abstract

A display device includes first to fifth insulating films, first to third conductive films, semiconductor film, a planarization layer, an organic resin film, a pixel electrode, an opposing electrode and a light-emitting member. The first insulating film includes nitrogen. The second and third insulating films include oxygen. The fifth insulating film is an inorganic insulating film. The fourth insulating film, the fifth insulating film, the planarization layer and the organic resin film include first to fourth opening, respectively. An edge portion of the third opening and an edge portion of the fourth opening are rounded. Part of the third conductive film and part of the planarization layer are located in the second opening. Part of the pixel electrode and part of the organic resin film are located in the third opening. Part of the light-emitting member and part of the opposing electrode are located in the fourth opening.
