ABSTRACT:
A fluorescent liquid crystal display of the type for reflecting radiation comprises a fluorescent material contained within a liquid crystal material for providing fluorescence in response to absorbance, and a filter element for reflecting at least one of the fluorescence and the absorbance and, if necessary, for showing low reflection in connection with radiation except for the at least one of the fluorescence and the absorbance to thereby enhance display contrast of the display.
