Light-emitting device and light-emitting system

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.

1 . A light-emitting system comprising:
 a light-transmitting partition member that partitions a space from an exterior;   a light-transmitting substrate disposed on the partition member;   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 the outer side of the end.   
     
     
         2 . The light-emitting system according to  claim 1 ,
 wherein light emitted from the light-emitting unit is emitted to the side opposite to the side on which the partition member is located.   
     
     
         3 . The light-emitting system according to  claim 1 ,
 wherein light emitted from the light-emitting unit is emitted to the exterior through the partition member.   
     
     
         4 . The light-emitting system according to  claim 1 ,
 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.
