Abstract

We have fabricated a nematic liquid crystal (LC) cell associated with the transition of the liquid crystal director from a twist to a twisted bend alignment, where an initial transition voltage is not required unlike in the case of the conventional optically compensated bend (OCB) cell. For the device which is initially in the twist state, the molecular deformation occurs continuously from twist to bend alignment without forming nucleations with increasing voltage and initial setting voltage for transition. The device exhibits, a wide viewing angle with compensated films and a fast response time of less than 10 ms.
