A cover member 107 is adhered onto a substrate 101 on which an EL element is formed with a filler 208 as an adhesive. Further, a sealing member 209 is provided so as to cover a side surface (an exposing surface) of the filler 208, and a frame member 108 is adhered using the sealing member 209. With this structure, the EL element is completely sealed by the filler 208, and shut from moisture and the like from the outside. Thus, deterioration of an EL layer due to oxidization can be prevented.
