Method for manufacturing organic light-emitting device and method of manufacturing display unit
View Patent ↗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.
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 light-emitting organic 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.
2. The method of manufacturing the organic light-emitting device according to claim 1 , wherein the first mask includes one of a fluorine resin, a water-soluble resin, and an alcohol-soluble resin.
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 use of a solvent not allowing the first organic layer to be dissolved therein.
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 first organic material, and then
a second mask is selectively formed in a second region on 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.
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. A method of manufacturing a display unit comprising:
forming an organic light-emitting device, the forming of the organic light-emitting device including
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.
