A light-emitting device includes a light-transmitting substrate, a light-transmitting interconnect located over the substrate, an insulating layer located over the substrate and the interconnect, and an intermediate layer formed in at least a region of a lateral side of the interconnect that overlaps the insulating layer.

Light-emitting device including a light-transmitting interconnect located over a substrate

A substrate () is a light-transmitting substrate. A light-transmitting first electrode () is formed over the substrate (). An insulating layer () is formed over the substrate () and the first electrode () and includes an opening () overlapping the first electrode (). An organic layer () is located within at least the opening (). A light-transmitting second electrode () is formed over the organic layer (). An intermediate layer () is formed in at least a portion of a region of a lateral side of the first electrode () overlapping the first electrode (). A refractive index of the intermediate layer () is between a refractive index of the substrate () and a refractive index of the first electrode ().
