An improved illuminated license plate comprising a support, an electroluminescent sheet, and a facing sheet. The support includes a rigid, nonopaque plate. The rigid support plate has a front surface and a back surface. An electroluminescent sheet is mounted on the back surface of the support plate, preferably in a recess provided in the back surface for such purposes. The facing sheet is nontransparent and is affixed to the front surface of the support plate. The facing sheet also has indicia perforated therethrough such that light emitted by the electroluminescent sheet passes through the perforated indicia illuminating the perforated indicia in contrast to the facing sheet. Preferably, the novel license plates also comprise optional colored translucent sheets mounted on the support plate between the electroluminescent sheet and the facing sheet to vary the apparent color of the light emitted by the electroluminescent sheet. Also, the facing sheet preferably is suitable as a substrate for printed indicia.
