Abstract
A high-precision display device is capable of suppressing a leak current and operating at a low power consumption. The display device comprises a source power supply for providing a pixel electric potential to each pixel placed on a substrate through a first thin-film transistor; a gate power supply for controlling conductive and nonconductive states of the first thin-film transistor; and a second thin-film transistor disposed between the first thin-film transistor and the gate power supply, the second thin-film transistor being controllable independently of the first thin-film transistor.
