A display apparatus is capable of performing a gradation display and a high-speed low-power-consumption display by controlling the colored state of each pixel to an appropriate state. A driving method for the display apparatus displays images through deposition and dissolution of a metal by impressing a predetermined voltage on each pixel. A voltage pulse or AC voltage having an amplitude of not more than a threshold for deposition of the metal is impressed, and a writing pulse or an erasing pulse is controlled according to the resultant current. Alternatively, an additional writing pulse is impressed when the current is lowered to or below a predetermined value, after the writing. Further, the state of the pixel is detected through the current, and a rewriting operation is selected according to the detected state.
