Description
Summary:Electric field-induced reorientation of liquid crystal droplets in holographic polymer-dispersed liquid crystal (HPDLC) transmission gratings was investigated. In-plane reorientation of the droplet directors was attained by the use of interdigitated ITO electrodes. Samples with different angles between the directions of the grating vector and the electrodes were analyzed. The results show that intrinsic alignment of the droplets induced by the structural field is similar to the alignment induced by an external field of 6E7 V/m, i.e., the droplet directors are strongly trapped along the direction of the grating vector.
