Abstract: The method for manufacturing a display device includes forming a light emitting element and a terminal on a substrate, forming a sealing film including a first inorganic insulating film and a second inorganic insulating film to cover the light emitting element and the terminal, forming a resist having a taper shape in which a thickness of an end portion on the sealing film becomes thinner as it goes to the terminal side by using a gray-tone mask, forming a taper shape in which thicknesses in end portions of the first inorganic insulating film and the second inorganic insulating film becomes thinner as it goes to the terminal side by etching, forming a touch electrode above the sealing film and forming wiring connected to the terminal via the end portions together with connecting to the touch electrode for detecting a touched position.
