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