Abstract
The liquid crystal display according to this invention comprises a liquid crystal cell having a pair of substrates with faced insides which are provided with electrodes, ferroelectric liquid crystal with a chiral smectic C phase in between said substrates and a polarizing plate on the light incidence side. One of said electrodes is a relfective electrode. The display is utilized with microcomputers, word processors, television or so on, and wherein, due to a small number of parts, the absorption loss of light is small and a reflective plate is prevented from being oxided and therefore degraded in reflection index, since it is not exposed to air.
