PROBLEM TO BE SOLVED: To provide the driving device of a display panel, capable of preventing calorific values of respective row electrode drive circuits from increasing, by substantially informing power consumption of the respective row electrode drive circuits of row electrode groups. SOLUTION: The drive device is provided with a plurality of row electrode groups, each of which is constituted of a plurality of row electrodes and a plurality of columnar electrodes which are arranged in a direction orthogonal to respective row electrodes of the row electrode groups and which form display cells at intersections with the row electrodes and in the device, a control circuit individually generates a control signal for every row electrode group and a row electrode drive circuit generates drive pulses, in response to the control signal and the circuit supplies the driving pulses to respective row electrodes, and moreover, the supply of a control signal from the control circuit to a row electrode driving circuit is delayed and controlled by each row electrode group.
