<p>PROBLEM TO BE SOLVED: To make a display sheet usable for both of a display for internal illumination and a display device for external illumination by providing one surface of a transparent sheet with a phosphor layer or a stimulable phosphor layer and providing the other surface with a tacky adhesive layer, thereby forming the display sheet. SOLUTION: The one surface of the transparent sheet 2 is provided with the resin sheet which is printed with a color layer 4 and the phosphor layer or the stimulable phosphor layer 1 in this order or contains the phosphors or stimulable phosphors and the other surface of the transparent sheet 2 is provided with the tacky adhesive layer 3. This display sheet is stuck by the tacky adhesive layer 3 to a glass plate or other transparent resin plate and is irradiated with UV rays from a display sheet side, by which the phosphor layer or the stimulable phosphor layer 1 of the display sheet is made to emit light. The emitted light is visible from the glass plate or transparent resin sheet side. There are no problems at all even if a UV absorbent is contained in the glass plate or transparent resin sheet. Then, the display sheet is usable for both of the display devices for internal illumination and external illumination and the colors bright even under visible light may be obtained.</p> |
