Abstract: A lighting device including an electroluminescent (EL) material is connected to an external power supply easily and the convenience is improved. In a lighting device having a light-emitting element including an electroluminescence (EL) layer, a housing including a light-emitting element has a terminal electrode electrically connected to the light-emitting element on a peripheral end portion. The terminal electrode provided on the housing so as to be exposed to the outside is in contact with a terminal electrode for the external power supply, so that the external power supply and the light-emitting element are electrically connected to each other and power can be supplied to the lighting device.

Abstract: To reduce power consumption of a display device with the use of a simple structure and a simple operation. The display device includes an input device. Input of an image signal to a driver circuit is controlled in accordance with an image operation signal output from the input device. Specifically, input of image signals at the time when the input device is not operated is less frequent than that at the time when the input device is operated. Accordingly, display degradation (deterioration of display quality) caused when the display device is used can be prevented and power consumed when the display device is not used can be reduced.

Abstract: An object is to provide a convenient display device which consumes sufficiently small amount of power and a method for driving such a display device. The display device can be in an off state with a still image displayed in a still image display mode in which a pixel electrode and a common electrode which are for applying a voltage to the display element are brought into a floating state so that a voltage applied to the display element is held, and a still image is displayed without further supply of a potential. The display device is put to an off state with a desired image displayed in the still image display mode, whereby the display device can have a higher level of security and can be more convenient.
