The present invention is to solve the problems of heat release and a metal material corrosion due to fluorine that are arisen in the case of using a film containing fluoroplastics (Teflon짰) as a protective film for a light-emitting device. In the present invention, an inorganic film is formed after forming a light-emitting device, and a film containing fluoroplastics is formed thereon for avoiding contact with a metal material for forming the light-emitting device, as a result, a metal material corrosion due to fluorine in the film containing fluoroplastics can be prevented. In addition, the inorganic insulating film has a function of preventing fluorine in the film containing fluoroplastics from reacting to the metal material (barrier property), in addition, the inorganic insulating film is formed of a material having high heat conductivity for releasing heat generated in a light-emitting device.
