PURPOSE: A circuit for driving the super twisted nematic(STN) liquid crystal display(LCD) panel is provided to reduce the size of the devices including the STN LCD panel, thereby saving the manufacturing cost. CONSTITUTION: A circuit for driving the super twisted nematic liquid crystal display panel includes a driving unit(410) and a power supplying unit(400). The driving unit(410) drives the electrodes in response to the driving voltage level control signal. And, the power supplying unit(400) selectively transmits a plurality of powers to the driving power lines connected to the driving unit(410).
