Abstract. New guest-host dyes of red and purple colour suitable for fabrication of ultrathin film polarizer from polymerizable liquid crystals are developed. When the absorption spectrum of dye matches the photopic curve, samples with total film thickness below 50 μm show good visual contrast.

Keywords: guest-host, polymerizable liquid crystal, thin film, polarizer.
