Using a side‐chain mesogenic polymer stabilized ferroelectric liquid crystal display (PS‐FLCD) cell together with a two dimensional array of red, green and blue light emitting diodes (LEDs) as a modulated back light unit, we constructed a field sequential fullcolor (FSC) LCD. The PS‐FLCD used in this research exhibits high contrast ratio (230:1) with thresholdless monostability, grayscale capability, and fast response speed (τ=40 μ sec). In the present research it is taken the advantages of the favorable characteristics of the PS‐FLCD for implementing an FSC‐LCD that has an 8×8 matrix format. The fabricated FSC‐LCD, which is operated at the frame rate of 330Hz, is shown to exhibit an excellent color gamut, color grayscale, and smearless moving color bars.
