ELECTROLUMINESCENT DEVICE AND APPARATUS

摘要

The present invention provides the EL device and apparatus each of which has a white appearance in the non-light-emitting state, and can emit white light with high luminance in the light-emitting state. When such an EL device or apparatus is used, the light-emitting surface provides a background with high whiteness both in the light-emitting and non-light-emitting state, and can highlight a light-transmitting printed layer formed on the light-emitting surface.
