We report a high birefringence and low viscosity nematic liquid crystal for phase‐only spatial light modulators (SLMs). To achieve 2π phase change at λ = 633 nm with 5 V operation voltage, the measured response time is 2.2 ms at 50°C. Meanwhile, our mixture exhibits no sign of photodegradation for a total dosage of 20 MJ/cm 2 at a blue laser wavelength λ = 465 nm Widespread applications of this material for high brightness SLMs, LIDAR, near‐eye displays, and head‐up displays are foreseeable.
