A display device free from a deterioration in luminescence efficiency is provided. In the display device of the present invention, since an inorganic film is formed after concave parts in which luminescence portions are positioned are filled with a filling film, no crack is formed in the inorganic film. Since the inorganic film is made of a material having high gas tightness and heat conductivity (such as, diamond-like carbon or AlN), water and oxygen will hardly penetrate the luminescence portions, and heat of the luminescence portions will be conducted to the inorganic film, so that the luminescence portions do not reach high temperatures. Further, since a gap between first and second panels is filled with a resin film, the atmosphere does not enter from the outside. Because the luminescence portions are free from damage from water, oxygen and heat, the display device of the present invention has a prolonged life.
