PROBLEM TO BE SOLVED: To attain higher image quality and price-reduction by facilitating the adjustment of output timing of a module for drive of a display panel. SOLUTION: This module 1 for drive of a display panel applies a high voltage pulse to each electrode group arrayed into a matrix form, and excites an intersection part of an orthogonal electrode to perform display. A power part 2 for performing pulse driving of the each electrode group at high voltage and a control part 3 for transmitting a pulse for drive of each electrode to the power part 2 at prescribed timing are mounted on the same substrate. On the substrate, a propagation time adjustment circuit 4 for varying the transmission timing of the pulses for drive is mounted. In this configuration, since the apply timing of high-voltage pulse can be adjusted with a module single body, the degree of difficulty of scattering adjustment is relieved drastically, and conventional parts selection and timing adjustment after device assembling can be eliminated, so that drastic man-hour reduction and cost reduction can be carried out.
