ABSTRACT:
A display device selectively provides a first and second displays. A first light source emits first light, and a second light source emits second light having peak wavelength different from the first light, and a translucent sheet hit selectively by one of the first and second lights. The translucent sheet has first printed area parts formed on a first surface of the sheet to pass only the first light for providing the first display, second printed area parts formed on the first surface to pass only the second light for providing the second display, third printed area parts formed on the first surface to prevent light transmittance, and printed dimmer area parts formed on a second surface at areas corresponding to overlapped area parts of the first and second displays so as to suppress the first and second lights.
