摘要
A full spectrum black-and-white chiral nematic liquid crystal display is presented comprising a chiral nematic liquid crystal cell of controllable planar structure and focal conic structure, the cell comprising chiral nematic liquid crystal material between two transparent substrates having electrodes; and the cell being arranged between two circular polarizers, wherein at least one circular polarizer is of opposite handedness to the chiral nematic liquid crystal material. In some configurations there may be a light source. Embodiments of transmissive and transflective type displays are presented in which both front and rear circular polarisers have the same handedness or the front polariser has the opposite handedness to the liquid crystal medium and the rear polariser.
