Abstract

We demonstrate a fast switching surface polymer-assisted vertically aligned (SPA-VA) liquid crystal (LC) cell. The deposition of the polymer nano spikes as a part of the alignment layer is achieved by polymerizing a small amount of a reactive monomer in vertically aligned liquid crystal in the absent of an applied voltage. The phase-separated polymer localized at the both substrate surfaces and formed nano-sized spikes. These polymer nano-spikes act as internal surface alignment layers and enhance the speed of field-induced reorientation of liquid crystal molecules.
