Abstract
An illuminated display device includes a housing having front and rear openings with which to register outer transparent face plates and superimposed inner thermoplastic translucent sheets having inwardly convex, relatively thin thermoformed logos projecting inwardly. The logos are preferably hemispheres or portions thereof, and are coated with fluorescent layers and an opaque layer is sandwiched between each sheet and plate in registry with the non-logo area of the sheets. A fluorescent lamp is disposed in the housing between the sheet-plate pairs for self contained units and can be open, such as at the top, to receive outside light.
