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.
