the present invention relates to an electroluminescent element comprising at least a substrate , an electrode formed on the substrate and an electric light emitting layer and to a display using this element as pixel unit . the object of the present invention is to provide a display without property deterioration due to heating of the el layer or remaining of the solvent , and is practical though the thickness of the film is uneven . a display comprising the electroluminescent element , wherein the light emitting region is changed by the applied voltage , as a pixel unit wherein the display is driven by a digital gradation driving method in which a low voltage value at which the pixel dose not emit light is a non - selected state , and a high voltage value at which the light emitting region within the pixel is saturated is a selected state . by using the present invention , though the film thickness is not even , a practical display with excellent gradation control property can be provided .
