Abstract:
A light-emitting device, a lighting device, a display device, or the like in which the state of a back surface side can be observed when light is not emitted is provided. The light-emitting device includes a plurality of light-emitting portions and a region transmitting visible light in a region other than the light-emitting portions. Alternatively, the light-emitting device includes a plurality of light-transmitting portions transmitting visible light and a light-emitting portion that can emit light in a region other than the light-transmitting portions. When light is not emitted, the state of a back surface side of the light-emitting device is visible through the region transmitting visible light. When light is emitted, the state of the back surface side of the light-emitting device can be made less visible by diffusion of light emitted from the light-emitting portion.
