Zusammenfassung:	A PCB and an LCD using the same are provided to re-discharge static electricity, induced through a bottom chassis between a ground area of a PCB and a ground contact unit connected to the bottom chassis, to the bottom chassis. A control PCB(Printed Circuit Board)(170) comprises connectors(171,172), a static electricity protection unit(174) and a ground contact unit(176). The ground contact unit is contacted with a bottom chassis. The static electricity protection unit electrically connects the ground contact unit with a ground line(178) connected to a driving circuit. The static electricity protection unit re-discharges static electricity, induced through the bottom chassis, to the bottom chassis. The driving circuit comprises a timing controller(134) and a power supply unit(136).
