Method of manufacturing a display device and a display device

A display device that includes a plurality of pixels, comprising:

• a rib formed at a peripheral part of the pixels;
• a first inorganic film formed over the rib;
• a first organic film formed so as to be in contact with the first inorganic film in a region over a vicinity of a border between a horizontal surface and an inclined surface of the rib;
• a second inorganic film formed so as to cover the first inorganic film and the first organic film;
• a second organic film formed so that its upper surface is positioned lower than that of the second inorganic film over a top surface of the rib and that its upper surface is formed to be planarized by filling a concave part constituted by a horizontal surface and an inclined surface of the second inorganic film;
• and
• a third inorganic film formed so as to cover the second inorganic film and the second organic film,
• wherein the second organic film is formed to be thicker than the first organic film.
