采用反应性液晶（RM）作为配向层，提高了采用平凸透镜结构的双折射液晶（NLC）制作的偏振无关微透镜阵列的开关速度。由于NLC旋转方向由聚合的RM预定，从垂直取向到螺旋取向的直接切换在不经历亚稳展曲状态的情况下获得，这引起在具有偏振独立性的垂直取向NLC微透镜中的缓慢响应。
The switching speed of a polarization-independent microlens array fabricated with a nematic liquid crystal (NLC) in the configuration of a plano-convex lens is improved by the reactive mesogen (RM) mixed in an alignment layer. Due to the NLC rotating directions predetermined by the polymerized RM, the direct switching from a vertical alignment to a spiral one is obtained without going through a metastable splay state, which gives rise to slow response in the vertically aligned NLC microlens with polarization independence.
