Abstract
A display apparatus according to this invention includes a plurality of pixels, each of which is supplied with a pixel data; a pixel capacitance for accumulating an electric charge in accordance with the pixel data; a holding capacitance provided to each of the pixels to hold the pixel data; and a buffer amplifier for supplying the electric charge to the pixel capacitance in accordance with the voltage of the holding capacitance. Another display apparatus of this invention includes a plurality of pixels, each of which is supplied with a pixel data; a pixel capacitance for accumulating an electric charge in accordance with the pixel data; a first holding capacitance provided to each of the pixels in order to hold the pixel data; a display changing circuit which is controlled to be turned on/off by a display changing signal; a second holding capacitance which is supplied with the electric charge by the first holding capacitance via the display changing circuit; and a buffer amplifier for supplying the electric charge to the pixel capacitance in accordance with the voltage of the second holding capacitance.
