A device for driving a liquid crystal display device, including, a segment signal output circuit for supplying segment signals to segment electrodes of the liquid crystal display device, a level of each of the segment signals being changed according to a level of corresponding one of data signals received by the segment signal output circuit, and a back plate signal output circuit for supplying a back plate signal having a predetermined level to back plate electrodes of the liquid crystal display device in succession. The segment signal output circuit is adapted to shift a level of each of the segment signals, for a short period of time at least shortly prior to change of level of corresponding one of the data signals, to such a value that electric charges charged up in a corresponding liquid crystal cell are discharged within the short period of time.
