Abstract
Fluorescent displays are comprised of a means for cooperatively aligning a liquid crystal material and a fluorescent medium disposed therein. The fluorescent medium is comprised of a nematic liquid crystal host which is effectively transparent to radiation of both near ultraviolet and visible wavelengths and a fluorescent guest whose visible fluorescent intensity varies with the phase or orientation of the liquid crystal host.
