A method of controlling an electro-optical element that includes a memory type electro-optical layer between a pixel electrode and a common electrode is described. The method includes suspending supplying power to a display driving circuit and a latch circuit and subsequently resupplying power to the display driving circuit. The method includes subsequently applying a first voltage to the common electrode using the display driving circuit and subsequently applying a second voltage to the common electrode using the display driving circuit. The second voltage (i) is different from the first voltage and (ii) varies a potential of the pixel electrode according to a charge state of the memory type electro-optical layer. The method includes subsequently applying a third voltage to the common electrode using the display driving circuit, wherein the third voltage is between the first voltage and the second voltage. The method further includes subsequently resupplying power to the latch.
