Abstract:
A self-light emitting device and an electrical appliance including the same are provided, in which extracting efficiency of light from a light emitting element, especially in an EL element, can be improved. A light scattering body formed by etching a transparent film is provided on an insulator so that the extracting efficiency of light can be improved, and the self-light emitting device with high efficiency of light emission can be provided.
