Abstract
A light-emitting portion (140) is formed on a first surface (S1) of a substrate (100), and includes a light-transmitting first electrode (110), a light-reflective second electrode (130), and an organic layer (120) located between the first electrode (110) and the second electrode (130). A light-transmitting region is located between a plurality of light-emitting portions (140). A cover member (200) covers the light-emitting portions (140). A low refractive index layer (400) is located on the first surface (S1) side of the substrate (100), and has a refractive index nL lower than a refractive index nS of the substrate (100).
Claims13
A light-emitting device comprising:
- a light-transmitting substrate;
- a plurality of light-emitting portions, formed on a first surface of the substrate, which include 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 located between the plurality of light-emitting portions;
- a cover member that covers the light-emitting portions;
- and
- a low refractive index layer, located on the first surface side of the substrate, which has a refractive index nL lower than a refractive index nS of the substrate.
A light-emitting system comprising:
- a light-transmitting partition member that partitions a space from an outside;
