Abstract: A liquid crystal display device includes an optical sensor provided near an end portion of a liquid crystal display panel, a pixel provided in a display region of the liquid crystal panel, and a monitoring pixel. The optical sensor detects illuminance of light delivered from the liquid crystal display panel side. The pixel for which a transistor whose off-state current is low and the monitoring pixel are supplied with a potential to display a still image, at least light transmitted through a liquid crystal layer of the monitoring pixel is detected by the optical sensor, and the pixel in the display region of the liquid crystal display panel and the monitoring pixel are supplied again with a potential when a rate of change in illuminance reaches a predetermined value, so that the still image is kept being displayed.

Abstract: The still image display mode includes a first period of writing the data of the image signal from the driver circuit portion into the pixel; after the first period, a second period of stopping supply of a signal or voltage for operating the driver circuit portion to the driver circuit portion; and after the second period, a third period of restarting the supply of a signal or voltage for operating the driver circuit portion to the driver circuit portion and writing the data of the image signal into the pixel from the driver circuit portion, so that the pixel keeps displaying a still image. A length of a period from the stop of the supply of the signal for operating the driver circuit portion to the driver circuit portion to the restart is set in accordance with a temperature of the display device.
