Abstract

One embodiment of the present invention is an organic EL device including a substrate and a sealing substrate, both substrates being attached to each other, the substrate including a first electrode formed on the substrate, an organic EL layer formed on the electrode and a second electrode formed on the organic EL layer, and the sealing substrate having a moisture capture agent layer formed on a surface of the sealing substrate on the substrate side, wherein a space between the substrate and the sealing substrate is filled with an injection material.

Claims

1. An organic electroluminescence device, comprising:

a first electrode formed on a substrate;

an organic electroluminescence layer formed on said first electrode;

a second electrode formed on said organic electroluminescence layer;

a sealing substrate having a moisture capture agent layer, said moisture capture agent layer being formed on a surface which faces said substrate; and

an injection material filled in a space between said substrate and said sealing substrate,

wherein said substrate is attached to said sealing substrate.

2. The organic electroluminescence device according to claim 1,

wherein said first electrode formed on said substrate is a reflective electrode and said second electrode formed on said organic electroluminescence layer is a transparent electrode.

3. The organic electroluminescence device according to claim 1,
