Abstract
A partition member (20) partitions a space occupied by a person from the outside. The space is, for example, an interior of a mobile object (30) such as a vehicle. A substrate (100) is disposed on a surface of the partition member (20) on the space side and has optical transparency. On a surface (a second surface (110b)) of the substrate (100) on the space side, a plurality of light-emitting units and an insulating layer (150) are disposed. Each light-emitting unit (140) includes a light-transmitting first electrode (110), an organic layer (120), and a second electrode (130) in this order from the external side. The insulating layer (150) defines the plurality of light-emitting units (140). A third region (106: a light-transmitting region) in the substrate (100) in which the second electrode (130) and the insulating layer (150) are not formed is provided between light-emitting units (140) next to each other.
