Organic luminescence device with anti-reflection layer and organic luminescence device package

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.

1 .- 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.  
   
   
       21 . The organic luminescence device according to claim  3 , wherein the anti-reflection layer has a refractive index less than the second electrode.  
   
   
       22 . The organic luminescence device according to claim  3 , wherein the anti-reflection layer is a single layer.  
   
   
       23 . The organic luminescence device according to claim  3 , wherein the anti-reflection layer is multi-layers.
