Method of manufacturing organic light-emitting device and method of manufacturing display unit

Abstract

There is provided a method of manufacturing an organic light-emitting device including: forming a first organic material layer on a substrate; and forming a mask in a first region on the first organic material layer, and then selectively removing the first organic material layer to form a first organic layer in the first region.

The application is claimed as follows: 
     
         1 . A method of manufacturing an organic light-emitting device comprising:
 forming a first organic light-emitting material layer on a substrate;   thereafter selectively forming a first mask in a first region on and in direct contact with a portion of the first organic light-emitting material layer, and then   selectively removing the first organic light-emitting material layer which is not in the first region to form a first organic layer,   wherein the first mask is formed of a resist material.   
     
     
         2 . The method of manufacturing the organic light-emitting device according to  claim 1 , wherein the first organic light-emitting material layer is formed with use of an evaporation method. 
     
     
         3 . The method of manufacturing the organic light-emitting device according to  claim 1 , wherein after the first organic layer is formed, the first mask is removed with the use of dry etching. 
     
     
         4 . The method of manufacturing the organic light-emitting device according to  claim 1 , wherein the first mask is formed by a reverse offset printing method. 
     
     
         5 . The method of manufacturing the organic light-emitting device according to  claim 1 , further comprising forming a second organic layer after the first organic layer is formed. 
     
     
         6 . The method of manufacturing the organic light-emitting device according to  claim 5 , wherein
 a second organic light-emitting material layer is firstly formed on the first organic layer and the substrate, and then   a second mask is selectively formed in a second region on and in direct contact with a portion of the second organic light-emitting material layer, the second region is different from the first region, and thereafter   the second organic light-emitting material layer is selectively removed to form the second organic layer in the second region.   
     
     
         7 . The method of manufacturing the organic light-emitting device according to  claim 6 , wherein after the first organic layer and the second organic layer are formed, the first mask and the second mask are removed with the use of dry etching. 
     
     
         8 . The method of manufacturing the organic light-emitting device according to  claim 6 , wherein the second organic light-emitting material layer is formed with use of an evaporation method. 
     
     
         9 . The method of manufacturing the organic light-emitting device according to  claim 6 , further comprising forming a third organic layer after the first and second organic layers are formed. 
     
     
         10 . The method of manufacturing the organic light-emitting device according to  claim 9 , wherein
 a third organic light-emitting material layer is firstly formed on the first and second organic layers and the substrate, and then   a third mask is selectively formed in a third region on and in direct contact with a portion of the third organic light-emitting material layer, the third region is different from the first region and the second region, and thereafter   the third organic light-emitting material layer is selectively removed to form the third organic layer in the third region.   
     
     
         11 . The method of manufacturing the organic light-emitting device according to  claim 10 , wherein after the first organic layer, the second organic layer and the third organic layer are formed, the first mask, the second mask and the third mask are removed with the use of dry etching.
