Patent attributes
A method of reducing power consumption of an electro-optical display device which can display a still image with the use of analog signals. A circuit in which a small amount of leakage current flows between a source and a drain of a selection transistor when the selection transistor is off; the source of the selection transistor is connected to a gate of an N-channel driving transistor, a gate of a P-channel driving transistor, and one electrode of a capacitor; and a source of each of the N-channel driving transistor and the P-channel driving transistor is connected to one electrode of a display element is provided in each pixel. The longest time of one frame is set to 100 seconds or longer with the use of such a circuit, whereby power consumption at the time of rewriting is reduced.
