A new reflective display mode for antiferroelectric liquid crystal

Abstract In this work, we proposed a reflective antiferroelectric liquid crystal display (AFLCD) using a half‐wave cell whose in‐plane tilt angle is 22.5°. To check the validity of our design, we fabricated a reflective half‐wave AFLC cell of which in‐plane tilt angle is 24.9°, and measured VIS reflection spectra, contrast ratio and response time. In the results, the half‐wave AFLC cell in the reflective configuration exhibits high brightness, high contrast ratio of 20:1. and fast response time of 700 μs.
