Organic Electroluminescence Pixel, Organic Electroluminescence Device, and Manufacturing Method Thereof

Abstract

An organic electroluminescence pixel, an organic electroluminescence device comprising the same, and method for manufacturing the organic electroluminescence device are provided. The organic electroluminescence pixel comprises a substrate, a first electrode, a first carrier-injection layer, a semi-trans-flective metal layer, an organic emitting layer, and a second electrode. The first electrode is formed on the substrate. The first carrier-injection layer, the semi-trans-flective metal layer, and the organic emitting layer are formed between the first electrode and the second electrode. At least one of the first electrode and the second electrode comprises a transparent electrode.

What is claimed is: 
     
         1 . A method for manufacturing an organic electroluminescence (OEL) device, comprising the steps of:
 providing a substrate;   forming a first electrode on the substrate;   forming a first pixel on the first electrode, comprising the steps of:
 forming a first carrier-injection layer (CIL); 
 forming a semi-trans-flective metal layer; and 
 forming an organic emitting layer; and 
   forming a second electrode on the first pixel;   wherein at least one of the first electrode and the second electrode comprises a transparent electrode.   
     
     
         2 . The method of  claim 1 , wherein the semi-trans-flective metal layer is formed on the first electrode. 
     
     
         3 . The method of  claim 1 , wherein the semi-trans-flective metal layer is formed between the first CIL and the organic emitting layer. 
     
     
         4 . The method of  claim 1 , wherein the semi-trans-flective metal layer is formed inside the organic emitting layer. 
     
     
         5 . The method of  claim 1 , further comprising:
 forming a second pixel on another first electrode, comprising:
 forming another first CIL; and 
 forming another organic emitting layer; and 
   forming the second electrode on the second pixel.
