PURPOSE: A driving circuit of a liquid crystal display(LCD) is provided, which realizes a source driving with a dot inversion method using a DAC(Digital Analog Converter) of one type. CONSTITUTION: The first and the second data latch part(21,22) latch source data in sequence by considering on time of a gate line and then output it. A DAC(Digital Analog Converter)(23) a latch output signal of the second data latch part into an analog signal. A driving signal processing block(24) outputs a signal of a region opposite to a conversion region of the DAC by receiving a signal being output from the DAC. A MUX(25) receives an output signal of the DAC and an output signal of the driving signal processing block as inputs(IN0,IN1) and then outputs them selectively by a polarity signal. And a buffer(26) buffers a signal being selected and output from the MUX.
