An optically compensated birefringence liquid crystal alignment agent. The liquid crystal alignment agent includes one or more polymerizable monomers polymerized to form a polymer having liquid crystal alignment memory on an alignment layer by irradiating an energy ray. Liquid crystals are rapidly converted from splay state to bend state along the polymer memory direction so that a liquid crystal display reaches steady state immediately by only applying normal voltage, without application of high voltage. The invention also provides a liquid crystal display including the liquid crystal alignment agent and a method for fabricating the liquid crystal display.
