Abstract
A plurality of light-emitting units (140) are provided on a first surface (100a) of a substrate (100) and are separated from each other. Each light-emitting unit (140) includes a light-transmitting first electrode (110), an organic layer (120), and a light-reflective second electrode (130). The organic layer (120) is located between the first electrode (110) and the second electrode (130). A light-transmitting region is located between the light-emitting units (140) and transmits light in the thickness direction of a light-emitting device (10). An optical filter (200) overlaps the light-transmitting region and does not overlap the plurality of light-emitting units (140).
