A display apparatus includes a pixel array section and a drive section that drives the pixel array section. The pixel array section includes first scanning lines and second scanning lines arranged in rows, signals lines arranged in columns, matrix pixels that are provided at a position where the first scanning lines, the second scanning lines, and the signal lines cross, a power line that supplies power to each of the pixels, and an earth line. The drive section includes a first scanner that sequentially line scans the pixels per each row by sequentially supplying a first control signal to each of the first scanning lines, a second scanner that sequentially supplies a second control signal to each of the second scanning lines in conjunction with the sequential line scanning, and a signal selector that supplies video signals to the columns of signal lines in conjunction with the sequential line scanning.
