PI-1185 ABSTRACT An electroluminescent device is adapted to serve as the dial of a conventional analog timepiece by providing it with a central aperture for the stem carrying the timepiece hand and inscribing the upper surface thereof with conventional time - indicating indicia, so that it can be read as a normal watch dial. The electroluminescent device provides either an illuminated or a non-illuminated dial for the timepiece and is preferably constructed of a transparent insulating substrate with timekeeping indicia on one surface and an electrically conductive layer on the other surface, a second layer adhered thereto comprising an electroluminescent mixture of phosphor particles dispersed within a polymeric resin binder, a third thin layer of insulating moisture resistant barrier material and a fourth layer of electrically conductive material of reflective metal. The phosphor size range is selected with respect to a minimum spacing between the conductive layers to reduce the voltage required to actuate the electroluminescent dial.
