Organic light-emitting device, and method for manufacturing organic light-emitting device

Abstract

The present invention provides an organic light-emitting device which can prevent a covering member from being damaged or peeled off, and which can be manufactured with excellent productivity and cost performance; and a method for manufacturing the organic light-emitting device. The covering member has a chamfer formed on the side of a face of the covering member on a reverse side to the side of an organic light-emitting element.

1 . A method of manufacturing an organic light-emitting device which includes a substrate; an organic light-emitting element arranged on the substrate and including a pair of electrodes and an organic compound layer formed between the pair of the electrodes; a covering member arranged on the organic light-emitting element, for covering the organic light-emitting element; and an adhesive member for adhering an end of the covering member and an end of the substrate, the method comprising:
 a step of arranging, on the organic light-emitting element, the covering member having a chamfer formed on a side of one face thereof so that a face of the covering member on a reverse side to the one face faces to a side of the organic light-emitting element; and   a step of adhering a side part of the covering member and a face of the substrate on a side of the covering member by dripping the adhesive member to the chamfer from above of the one face.   
   
   
       2 . The method for manufacturing the organic light-emitting device according to  claim 1 , wherein the adhering step is a step of dripping the adhesive member on the chamfer formed on each of four sides of a perimeter of the covering member to adhere the covering member and the substrate. 
   
   
       3 . An organic light-emitting device comprising:
 a substrate;   an organic light-emitting element formed on the substrate, and including a pair of electrodes and an organic compound layer formed between the pair of the electrodes;   a covering member arranged on the organic light-emitting element, for covering the organic light-emitting element, the covering member having a chamfer formed on a side of a face thereof on a reverse side to the organic light-emitting element; and   an adhesive member for adhering the substrate and the covering member by adhering a side part of the covering member and a face of the substrate on a side of the covering member.   
   
   
       4 . The organic light-emitting device according to  claim 3 , wherein the chamfer has a chamfered length of 0.2 mm or more. 
   
   
       5 . The organic light-emitting device according to  claim 3 , wherein the covering member is a flat glass plate. 
   
   
       6 . The organic light-emitting device according to  claim 3 , wherein the covering member is a glass plate having an etched face on the side of the organic light-emitting element. 
   
   
       7 . The organic light-emitting device according to  claim 3 , wherein the covering member is a circular polarizing plate.
