Abstract:
According to one embodiment, a light-emitting device includes a light-transmitting layer including first and second regions and a third region intervening therebetween, and a light-emitting portion overlapping the second region or the second and third regions. A first portion of the device corresponding to the first region transmits light having a certain wavelength in a visible range at a first transmittance. A second portion of the device corresponding to the second region causes emission by the light-emitting portion and transmits the light at a second transmittance lower than the first transmittance. A third portion of the device corresponding to the third region is configured to have a transmittance distribution in which transmittance for the light decreases from an end on a first portion's side to an end on a second portion's side within a range from the first transmittance to the second transmittance.
