In this letter, we experimentally verify the operation of a single-polarizer reflective bistable twisted nematic (BTN) liquid-crystal display using an optimized geometry. Based on the polarization optimization using the Poincaré sphere representation, several optimized operating modes, which can simultaneously optimize both bistable states, are possible. One of these optimized configurations, the 67.38° and −292.62° twisted bistable states with 310.69 nm birefringence and a 24.25° incident polarization angle, is studied in detail. The evolution of the state of polarization of light passing through this reflective BTN structure is numerically studied, and the electro-optic property of the reflective BTN structure is experimentally demonstrated. Our results show that, using these optimum configurations, a high-contrast display is possible.
