Claims

[Scope of utility model registration request]

In an EL light-emitting element in which an EL laminate including an EL light-emitting layer is covered with a transparent film or film in the shape of a Sanderutsch, the EL
At least two opposite edges of one of the two transparent films formed larger than the shape of the laminate are bent toward the rear of the part that protrudes from the edge of the EL laminate. , the edge of the other transparent film is folded back toward the edge of the one transparent film so as to wrap around the edge of the EL laminate, and the edges of the two transparent films are overlapped; An EL light emitting device characterized by having overlapping edges of two transparent films tightly sealed together.
