Abstract
A display apparatus includes: a plurality of luminance modulation elements each modulated in luminance by a voltage of a positive polarity applied thereto, each of the luminance modulation elements being not modulated in luminance by a voltage of an opposite polarity applied thereto; a plurality of first lines electrically coupled to first electrodes of the plurality of luminance modulation elements; a plurality of second lines electrically coupled to second electrodes of the plurality of luminance modulation elements, the plurality of second lines intersecting the plurality of first lines; a first drive unit coupled to the plurality of first lines, the first drive unit outputting scanning pulses; and a second driver unit coupled to the plurality of second lines. The first drive unit sets the first lines in a nonselection state to a high impedance state having a higher impedance as compared with the first lines in a selection state.
