Organic electroluminescent light emitting device and method for manufacturing same

Abstract

Provided is an organic electroluminescent light emitting device that can prevent moisture and/or oxygen permeation to thereby suppress degradation and that has increased light extraction efficiency. The organic electroluminescent light emitting device includes an organic electroluminescent element including an optically transparent first electrode, a light emitting function layer composed of two or more layers including a light emitting layer, and a second electrode, which are stacked on a surface of an optically transparent substrate in that order. A functional scattering section is provided in contact with at least part of an end face of the optically transparent substrate. The functional scattering section is foamed of a resin composition including a scattering body having moisture absorption property and/or oxygen absorption property. With the functional scattering section, moisture and/or oxygen can be prevented from entering inside the device and the light extraction efficiency can be enhanced.
