Disclosed is a method of fabricating and apparatus of a flat plate display that is able to separate a substrate and an imprinting mold from each other with a relatively small force. The fabricating apparatus of a flat plate display includes an imprinting mold which is boned with a substrate to form a thin film pattern on the substrate, the imprinting mold comprising projections and grooves; and a movable separation part configured to rotatably move from a one side toward the other side of the imprinting mold to vacuum-absorb the imprinting mold.
