Abstract
A display apparatus includes a display panel including pixels arranged in a matrix, pixel electrodes provided to the pixels, respectively, a common electrode provided commonly to the pixels, and scanning lines and signal lines for supplying a voltage to the pixel electrodes. In addition, a drive circuit is connected to the common electrode, the scanning lines, and the signal lines, and a control circuit provides a signal to the drive circuit. The control circuit selectively switches between a display drive mode in which an image is displayed on the display panel through sequential scanning of the scanning lines and application of a variable voltage to pixels via the signal lines by the drive circuit and a rewriting drive mode in which selected pixels are rewritten into black or white through application of a voltage, which is higher than a range of the variable voltage, to the selected pixels on a scanning line selected by the drive circuit.
