Abstract
Abstract An illuminated display for large color transparencies includes a cabinet for housing a light source and providing a front opening. A laminate is mounted in the opening including front and rear sheets of clear plate glass, a color film transparency interposed between the glass sheets, a clear adhesive securing the transparency to the front sheet of glass, and a light-diffusing adhesive securing the transparency to the rear sheet of glass. The laminate forms a display medium which has the features of safety glass and which affords long-lasting protection for the transparency, yet it is economical enough that it may be replaced if desired without substantial replacement or installation costs.
