Display device

Abstract

An organic EL display device includes a first substrate, a plurality of organic EL devices arranged on the first substrate, a second substrate arranged above the first substrate, and a filling layer arranged between the first substrate and the second substrate, and displays an image on the second-substrate side. The organic EL display device is characterized in that: the organic EL devices each have a light-emission layer, a reflection electrode formed below the light-emission layer and reflecting light from the light-emission layer upwards, and an upper electrode formed above the light-emission layer and having a light transmission property and reflectivity; a structure for resonating the light emitted by the light-emission layer is formed between the reflection electrode and the upper electrode; and the filling layer includes fine particles for diffusing light exiting from the upper electrode added therein.

What is claimed is: 
     
         1 . A display device comprising:
 a first substrate;   a plurality of light-emission devices above the first substrate; and   a filling layer covering the plurality of light-emission devices,   wherein each of the plurality of light-emission devises includes:
 a light-emission layer; 
 a reflection electrode below the light-emission layer to reflect light from the light-emission layer; 
 a bank configured to cover an edge of the reflection electrode; and 
 an upper electrode above the light-emission layer and having a light transmission property and reflectivity, 
   the filling layer includes fine particles dispersed therein configured to uniformly diffuse the light in a visible wavelength region exiting from the upper electrode,   the filling layer spreads both above the light-emission layer and above the bank continuously, and   the fine particles are dispersed in the filling layer both above the light-emission layer and above the bank.   
     
     
         2 . The display device according to  claim 1 ,
 further comprising a protection layer covering the plurality of light-emission devices.   
     
     
         3 . The display device according to  claim 2 ,
 wherein the protection layer is between the upper electrode and the filling layer, and   the upper electrode and the filling layer are spaced at an interval which is smaller than the thickness of the filling layer.   
     
     
         4 . The display device according to  claim 2 ,
 further comprising a second substrate above the protection layer.   
     
     
         5 . The display device according to  claim 1 ,
 wherein the light-emission layer is between the reflection electrode and the upper electrode,   a first space between the reflection electrode and the upper electrode at one of the plurality of light-emission devices is different from a second space between the reflection electrode and the upper electrode at another of the plurality of light-emission devices.
