Organic electroluminescent display device and manufacturing method of organic electroluminescent display device

Abstract

The present invention provides a top-emission-type organic EL display device. In a top-emission-type organic EL display device which includes organic EL elements each of which is formed by stacking a reflective lower electrode, a function layer and a light-transmissive upper electrode in order, the upper electrode contains a plurality of fine particles which are made of a material different from a material of the upper electrode. The fine particles are preferably made of silica. A portion of the upper electrode may be provided below the fine particles and a portion of the upper electrode may be provided above the fine particles.

1 . An organic EL display device of top emission type which includes organic EL elements each of which is formed by stacking a reflective lower electrode, a function layer and a light-transmissive upper electrode in order,
 wherein a plurality of light-transmissive fine particles is arranged in a scattered manner in the upper electrode.   
     
     
         2 . An organic EL display device according to  claim 1 ,
 wherein the fine particles are made of silica.   
     
     
         3 . An organic EL display device according to  claim 1 ,
 wherein a portion of the upper electrode is provided below the fine particles, and a portion of the upper electrode is also provided above the fine particles.   
     
     
         4 . An organic EL display device according to  claim 1 ,
 wherein the fine particles have a size which is less than 10 μm.   
     
     
         5 . An organic EL display device according to  claim 4 ,
 wherein the fine particles have a size which is equal to or less than and equal to or more than 50 nm.
