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.
