Abstract:
1. An electrooptic device, comprising: a first substrate; a second substrate; an electrooptic substance sandwiched between the first and second substrates; first displaying electrodes disposed above the first substrate; switching elements disposed corresponding to the first displaying electrodes; data lines electrically connected to the switching elements; a second displaying electrode disposed above the second substrate so as to oppose the first displaying electrodes; a sampling circuit including first conductivity type transistors to sample the image signals involving polarity inversion with respect to center voltages of amplitudes of the image signals and feed them to the data lines; a data line driver circuit that includes a shift register to feed sampling circuit drive signals to gates of the first conductivity type transistors being further formed in the peripheral region; inverters having output sides connected to the gates of the first conductivity type transistors; a gate voltage varying unit that changes supply voltages of the inverters in response to the polarity inversion; and the sampling circuit drive signals being inputted to the gates via the inverters.
