A writing and display device for producing luminescent images upon application of pressure includes an opaque backing member which is coated to render the backing member with a smooth surface at least on one side thereof. The smooth surface of the backing member is laminated with a flexible plastic sheeting. A translucent or transparent sheet which contains a luminescent dye or pigment is disposed adjacent to and coextensive with the backing member. Upon application of pressure onto the sheet, the interfacing surfaces adhere to each other to thereby produce a luminescent image.
