Abstract
Abstract An organic electroluminescent display panel having a plurality of emitting portions includes; a substrate on which a plurality of first display electrodes corresponding to emitting portions are formed; electrical insulation ramparts projecting from the substrate for exposing at least portions of the first display electrodes respectively; organic function layers each including at least one organic electroluminescent medium formed on exposed portions of the first display electrodes; second display electrodes formed on the organic function layers; and each electrical insulation rampart having an overhanging portion projecting in a direction parallel to the substrate. The cathodes are patterned automatically without use of the photolithography.
