A driving circuit for driving a liquid crystal display comprising a frame memory for storing image data, a DAC for converting digital data from the frame memory into analog signal, a buffer circuit for performing current amplification on the output of the DAC and supplying the same, and a logic controller for controlling the frame memory, the DAC, and outward circuits, in reply to a logic signal from the outward, in which the image data stored in the frame memory is supplied to the DAC without being converted from parallel to serial and the total number of the DACs and the buffer circuits within the driving circuit for use in driving the liquid crystal display is less than the number of the respective data bus lines.
