ABSTRACT:
The present invention relates to an electroluminescent (EL) 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.
