An LCD panel having analog display mode and memory display mode includes a capacitive element and first to third switch elements. The first switch element turns ON during a first operation for writing pixel potential from a signal line to the capacitive element, and turns OFF during a second operation. The second and third switch elements turn OFF during the first operation. The second switch element turns ON during a readout period of a second operation, to read out the pixel potential from the capacitive element. The third switch element turns ON during a write period in the second operation, to rewrite the pixel potential into the capacitive element.
