ABSTRACT:
An electrooptic device of the invention is constructed that an electrooptic substance is sandwiched between first and second substrates. The first substrate is overlaid with first displaying electrodes, switching elements which are disposed corresponding to the electrodes, data lines which are electrically connected with the switching elements, and a sampling circuit which includes first conductivity type transistors for sampling and which samples image signals and feeds them to the data lines, the image signals involving polarity inversion with respect to the center voltages of the amplitudes of these image signals. The electrooptic device further includes a gate voltage varying unit which changes the gate voltages of the first conductivity type transistors in response to the polarity inversion of the image signals. Thus, in an electrooptic device, such as a liquid crystal device in which inversion drive is implemented, flickering is reduced as the sampling circuit is constructed of the first conductivity type transistors.
