A display panel drive device capable of preventing a malfunction caused by
the influence of electrical charge remaining in a display-panel discharge
cell, in which, in parallel with a switching element that connects each
electrode of the display panel to a reference potential, at least one of
a row electrode drive circuit and a column electrode drive circuit is
provided with a parallel switching element that connects each electrode
to the reference potential via a current limiting element. The residual
charge in the discharge cell on the display panel is discharged via a
bypass formed by this parallel switching element within a predetermined
period immediately after the device power supply is turned on.
