Abstract: The invention reduces power consumption when, for example, a mobile personal computer is in a power-saving mode or when a cellular phone is in a wait mode, in an electro-optical apparatus, such as a liquid crystal display of the subfield drive type used as a display apparatus for various apparatuses.

Abstract: A driving method of a display device in which the number of voltage levels of scanning lines during a non-selection period is only one, and the voltage level of a data line corresponding to a display element that presents no image is set to the voltage level of the scanning lines during the non-selection period. The power consumption of the display device is thus reduced. A minimum area of the entire screen of the device is used for image presentation while the remaining area is set to a display-off state (display-off mode) using the above driving method, and thus the power consumption of the display device, for example, in a standby state is reduced. Each of the display-enabled area and the display-off area is flexibly set. A combination of a multi-line driving method and the above driving method helps further reduce power consumption.
