An information distributing system for distributing data to at least one information processing terminal device from an information center storing data. A fastener including a threaded portion and a substantially cone shaped portion configured to mate with the tapered interior surface of the collar is placed within the collar and advanced to expand the collar to mount the circuit board. Next, a gate insulating layer covering the gate wire, a semiconductor layer, an ohmic contact layer, and a data conductive layer are sequentially deposited, and a photoresist pattern is formed on the data conductive layer.
