Abstract
An organic electroluminescent display device that displays a preformed image includes spaced anode and cathode electrodes, organic electrically conductive hole transport layer and electron transport layer disposed between the anode and cathode electrodes, and a preformed image layer formed between the organic electrically conductive hole transport layer and electron transport layers such layer having a region that is preformed to have at least one preformed image such that when a voltage is applied across the anode and cathode electrodes which will cause a preformed image to be displayed. Voltages are applied across the anode and cathode electrodes of the organic electroluminescent display device causes the emission of light for viewing the preformed image.
