Abstract
A light-emitting portion () is formed on a first surface (S) of a substrate (), and includes a light-transmitting first electrode (), a light-reflective second electrode (), and an organic layer () located between the first electrode () and the second electrode (). A light-transmitting region is located between a plurality of light-emitting portions (). A cover member () covers the light-emitting portions (). A low refractive index layer () is located on the first surface (S) side of the substrate (), and has a refractive index nlower than a refractive index nof the substrate ().
