Abstract

For realizing an organic luminescence device of a high efficiency, the present invention provides an organic luminescence device having an anti-reflection film on a transparent electrode or on a moisture prevention layer.

Claims

1-18. -18. (canceled)

19. An organic luminescence device comprising:

(a) a pair of mutually opposed electrodes, wherein said pair of electrodes are a first electrode provided on a substrate and a transparent second electrode;

(b) a moisture prevention layer provided on said transparent second electrode in contact therewith;

(c) an anti-reflection layer provided on said moisture prevention layer in contact therewith;

(d) an organic layer formed between said pair of electrodes; and

(e) a transparent cover member opposed to the transparent second electrode across a gaseous layer, wherein said anti-reflection layer has a refractive index which is between the refractive indexes of said moisture prevention layer and the gas of said gaseous layer.

20. The organic luminescence device according to claim 19, wherein said first electrode provided on the substrate side is capable of intercepting external light and preventing reflection of external light.
