<p>A liquid-crystal display comprises a light source producing activating light (20), a light-modulating layer such as a liquid-crystal layer (1) for modulating the light from the source, and an output means such as phosphor dots (11) responsive to the activating light that passes through the modulator. In order to reduce the damage that tends to be done to the fabric of the display by the UV light used in earlier designs of such displays, and to broaden the applicability of available optical materials and components, the light source in the present invention emits at visible wavelengths. Suitable phosphors are disclosed.</p> |
