Abstract:
1. A light-emitting device comprising: 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, wherein a first portion of the light-emitting device that corresponds to the first region transmits light having a certain wavelength in a visible range at a first transmittance, a second portion of the light-emitting device that corresponds to the second region causes light emission by the light-emitting portion and transmits the light having the wavelength at a second transmittance lower than the first transmittance, and a third portion of the light-emitting device that corresponds to the third region is configured to have transmittance distribution in which transmittance for the light having the wavelength decreases from an end on a side of the first portion to an end on a side of the second portion within a range from the first transmittance to the second transmittance.
