The spectral characteristics of light absorption and light emission processes in focal conic and homeotropic structures of smectic‐A liquid crystal containing dichroic dyes including fluorescent ones were obtained. The influence of dichroic dyes introduction on electro‐optical parameters of guest‐host liquid crystal mixtures is discussed. The results allow one to obtain high‐contrast monochrome or two colour grey‐scale images on a wide viewing angle multistable transflective SmA LCD (EASL DMD™, Electrically Addressable Smectic Liquid crystal Daylight Memory Display).
