Organic electroluminescent device and its method of manufacture

A method of manufacturing an organic electroluminescent device, the method comprising:

• forming a plurality of first electrodes on a substrate;
• defining pixels on the first electrodes by forming a plurality of banks on the substrate and the first electrodes, the plurality of banks being of an inorganic material;
• forming a plurality of separators in stripe shapes on the plurality of banks between the pixels, the plurality of separators being an organic material;
• forming organic Emitting Material Layers (organic EMLs), each having a predetermined color in each of the pixels;
• and
• forming a plurality of second electrodes on the organic EMLs, the plurality of banks, and the plurality of separators,
• wherein the plurality of separators are formed between the pixels in which organic EMLs having different colors from each other are formed,
• wherein the organic EMLs are formed by drying and baking liquid phase organic materials having predetermined colors after the liquid phase organic materials have been respectively arranged within the pixels,
• wherein the liquid phase organic materials are arranged within the pixels using a dispensing method,
• wherein the onganic EMLs have an upper convex shaped surface in contact with the plurality of second electrodes and a lower concave shaped surface in contact with hole transport layers.
