ABSTRACT:
A structure and a method of manufacturing the organic electroluminescent (EL) elements, patterns of icons on the display panel of organic EL elements are formed. Initially, ramparts are formed on a continuous surface of a transparent and conductive film, i.e. an indium-tin oxide (ITO) film, and ramparts determine patterns of icons, then organic function layers and electrodes are formed. Processes are compatible to a conventional method of manufacturing an array type display panel, to improve disadvantages of dividing processes of array type display panels and organic EL elements into two portions.
