A method of fabricating a thin film transistor liquid crystal display is provided. The optical element is supported by a first elastic member and reinforced by a reinforcing member arranged outside a beam effective range along a length of the optical element. These compounds are weak acids and release hydrogen ions according to their ionization constant keeping a constant level of oxy-halogenated ion. Injecting burst errors at the system level provides a network simulation that more realistically reflects the effects of burst errors on network performance.
