We discuss a configuration using vertically aligned deformed helix ferroelectric liquid crystals to create a tunable single panel full‐color reflective display without need for color filters or stacked panels. The narrow bandwidth of reflection coupled with the polarization insensitivity and fast response times enable strong and high purity reflection spectra. Thermal tunability is disclosed here to demonstrate potential performance of this device, followed by preliminary results of continuous in‐plane electrode tuning. The pitch deformation scaling with applied field coupled with the fast response times inherent for ferroelectrics with spontaneous polarization make this device an ideal candidate for low‐power reflective displays.
