In an electrooptical apparatus having a function allowing part of a display screen
to be in a display state and allowing the other to be in a non-display state, for
a non-display region, application voltages for scanning electrodes are fixed at
non-selection voltages, and application voltages for signal electrodes are fixed
at voltages similar to the case of a full-screen ON-display or a full-screen OFF-display
at least in a predetermined period. Therefore, power consumption in the partial
display state can be reduced.
