Abstract
AbstractWe proposed vertical alignment liquid crystal devices (VALCDs) in which the vertically aligned LC is surrounded by polymer wall, named locked‐super homeotropic (LSH) device. Although the device has advantages of wide‐viewing angle, spacer‐free and simple fabrication, it exhibited relatively slow rising response time due to undefined azimuthal tilting direction with bias voltage. To resolve the problem, we fixed pretilt angle of VA using the polymerization of reactive mesogen (RM) with bias voltage. Conclusively, dynamic stability of LC directors is improved, exhibiting a fast response time.
