Abstract
A light-emitting unit (140) is formed on 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 units (140). An insulating film (150) defines an end (142) of the light-emitting unit (140). A sealing member (200) is fixed to the light-emitting unit (140) directly or through an adhesive layer (210). In addition, a thickness of the substrate (100) is d, and a width of a portion of the second electrode (130) that is further on the outer side of the light-emitting unit (140) than the end (142) is W, d/2 W is established.
Claims3
A light-emitting device comprising:
- a light-transmitting substrate;
- a plurality of light-emitting units formed on the substrate, each light-emitting unit comprising 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 units;
- and
- an insulating film that defines an end of the light-emitting unit,
- wherein the second electrode comprises a portion that is located further on an outer side of the end,
- wherein the light-transmitting region comprises a region not overlapping the insulating film, and
- wherein, when a thickness of the substrate is d and a width of the portion of the second electrode that is further on the outer side of the light-emitting unit than the end is W, d/2≤W is established.
