Abstract:
A highly reliable lighting device is provided at low cost by using a simple structure and a simple process. A lighting device with improved convenience, which has a shape suitable for a purpose and can respond to diversified applications is provided. A light-emitting panel which includes a light-emitting element provided over a flexible substrate and including an electroluminescent (EL) layer (the panel is also referred to as an “EL film”) is put in a glass housing. The EL film is flexible and thus can be provided in a variety of forms in accordance with the shape of the glass housing.
