Abstract

A control circuit () performs a first process in which it is controlled so that power is supplied to a liquid crystal panel (AA) from a power generation circuit (), and a second process in which it is controlled so that the liquid crystal panel (AA) is driven based on an internal vertical synchronizing signal (Vs) of which a frequency is higher than that of an external vertical synchronizing signal (Vs), and a video center voltage (Dref) is applied to each pixel electrode () of the liquid crystal panel (AA), and performs a control so that the liquid crystal panel (AA) is driven based on the external vertical synchronizing signal (Vs), after repeatedly performing the second process with respect to a plurality of the internal vertical synchronizing signals (Vs), when a display control signal which instructs displaying of an image on the liquid crystal panel (AA) is supplied.
