Disclosed are an apparatus and method for fabricating a flat panel display device to realize easy separation of a substrate from an imprinting mold. The manufacture of the brace, strut, or link is performed in a cost effective manner. In addition, event handlers can be dynamically manipulated, such that recipients of events can be added or removed during runtime. The light-condensing sheet includes a plurality of reverse prism patterns which protrude toward the exiting surface, extend along an arc of a circle, and are arranged in a concentric circle structure. Embodiments of the device are made on a single substrate.
