Abstract

A fluorescent liquid crystal display device having a display area which comprises means for causing external excitation of the fluorescent liquid crystal display device, a fluorescent material which emits visible fluorescence, a liquid crystal material mixed with the fluorescent material, first means for preventing the propagation of the visible fluorescence toward a display area of the fluorescent liquid crystal display device while not being activated by the excitation means, and/or second means for enhancing the propagation of the visible fluorescence toward the display area of the same while being activated by the excitation means.
