Abstract
When an antiferroelectric liquid crystal (AFLC) cell is set between crossed polarizers for optical modulators or displays, it has low transmittance efficiency. This happens because AFLC materials have inherent tilt angles of typically 18 to 38 deg, not 45 deg. To improve the low transmittance efficiency, we propose a new optical configuration for antiferroelectric liquid crystal displays or devices, which also improves color dispersion. It consists of two crossed antiferroelectric liquid crystal cells. The characteristics of this dual-antiferroelectric liquid crystal display are simulated and experimented.
