A driving apparatus of liquid crystal display apparatus of the present invention has a changeover control circuit for controlling each switching of the inputs and outputs of first and second amplifier circuits. In the changeover control circuit, an offset voltage applied to a pixel by the first and second amplifier circuits is changed in its polarity for every predetermined number of frames in accordance with a switch changeover signal for operational amplifier and an alternation switch changeover signal input and the offset voltage is canceled by frames whose number is twice as many as the predetermined number of frames. This allows the circuit to cancel the offset voltage by the frames and to avoid that the display unevenness is discernible by human eyes, thereby ensuring to provide driving apparatus and driving method of liquid crystal display apparatus that can carry out the display with high quality.
