Light-emitting device

Abstract

A light-emitting system includes a light-emitting device, and a holding member holding the light-emitting device. The light-emitting device includes a light-transmitting substrate, a plurality of light-emitting units provided on a first surface of the substrate away from each other, 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 which is located between the light-emitting units, and through which light is transmitted in a thickness direction, and an optical filter that overlaps the light-transmitting region and does not overlap the plurality of light-emitting units. The holding member includes a pattern for giving light shielding characteristics.

1 . A light-emitting system comprising:
 a light-emitting device; and   a holding member holding the light-emitting device, wherein the light-emitting device comprises:
 a light-transmitting substrate; 
 a plurality of light-emitting units provided on a first surface of the substrate away from each other, 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 which is located between the light-emitting units, and through which light is transmitted in a thickness direction; and 
 an optical filter that overlaps the light-transmitting region and does not overlap the plurality of light-emitting units, and 
   wherein the holding member comprises a pattern for giving light shielding characteristics.   
     
     
         2 . The light-emitting system according to  claim 1 ,
 wherein the holding member comprises a first region overlapping the substrate and a second region located around the first region, and   wherein the pattern is located at the second region.   
     
     
         3 . The light-emitting system according to  claim 2 ,
 wherein a transmittance of the optical filter is higher than a transmittance of the second region.   
     
     
         4 . The light-emitting system according to  claim 1 , further comprising a light-transmitting insulating layer that defines the light-emitting unit,
 wherein the light-transmitting region comprises:
 a first light-transmitting region that overlaps the insulating layer and does not overlap the second electrode; and 
 a second light-transmitting region that overlaps neither the insulating layer nor the second electrode, and 
   wherein an edge of the optical filter overlaps the first light-transmitting region or the second light-transmitting region.   
     
     
         5 . The light-emitting system according to  claim 1 ,
 wherein an edge of the second electrode extends to an outside of the light-emitting unit, and   wherein an edge of the optical filter overlaps a region of the second electrode which is located outside the light-emitting unit.   
     
     
         6 . The light-emitting system according to  claim 1 , further comprising a light transmitting sheet member provided with the optical filter,
 wherein the optical filter is provided in a region of the sheet member which overlaps at least a portion of the light-transmitting region and is not provided in a region of the sheet member which overlaps at least a portion of the light-emitting unit.
