A ferroelectric liquid crystal-based display device comprising a light source, a reflective spatial light modulator, a light output, a beam splitter, and a shutter. The beam splitter is located and aligned relative to the light source, the light output, and the spatial light modulator such that light generated by the light source is reflected or transmitted towards the spatial light modulator, and then light reflected by the spatial light modulator is reflected or transmitted towards the light output. The shutter has both and OPEN and a CLOSED state, and may include ferroelectric liquid crystal material. The shutter may be located and aligned relative to the lights source and the beam splitter such that when OPEN it transmits the light generated by the light source towards the beam splitter, and when CLOSED it prevents transmission of the light generated by the light source towards the beam splitter. Alternatively, the shutter may be located and aligned relative to the light output and the beam splitter such that when OPEN it transmits the light reflected by the spatial light modulator towards the light output, and when CLOSED it prevents transmission of the light reflected by the spatial light modulator towards the light output. A color separator and a first, second and third reflective spatial light modulators may be used in place of the above-described spatial light modulator. The color separator is located and aligned such that a first, second, and third wavelength band from the light generated by the light source, after being transmitted or reflected by the beam splitter, is transmitted or reflected towards the first, second, and third reflective spatial light modulators, respectively. Each of the first, second, and third reflective spatial light modulators include ferroelectric liquid crystal material.
