ABSTRACT:
A composition for use in thermally-addressable liquid crystal display devices, comprising a smectic liquid crystal material and a helichromic compound possessing both a chromophoric moiety and an optically-active moiety. The helichromic compound is a circularly dichroic dye capable of propagating incident visible light in a circularly polarized manner so that all polarizations of the incident light are absorbed. The composition comprising the helichromic compound can be utilized in thermally-addressable liquid crystal display devices to provide a display which operates at lower voltages, with faster response times, and higher contrast ratios.
