摘要： The present invention provides an image display device that is capable of reducing the power consumption. The total power consumption of a level shifter is reduced by using a pulse of an oscillator circuit as an enable signal of a level shifter for amplifying the enable signal to be supplied to a group of level shifters. The image display device includes an oscillator circuit, a first level shifter, and a plurality of second level shifters, which are mounted on a substrate and formed with thin-film transistors. The plurality of second level shifters each has a shutdown function for reducing the power consumption of the level shifters. The shutdown function of the first level shifter is controlled by an output pulse of the oscillator circuit. The shutdown function of the group of second level shifters is controlled by an output pulse of the first level shifter.

The second region of the polycrystalline semiconductor layer includes a first impurity diffusion region and two second impurity diffusion regions opposite in conductivity type to the first impurity diffusion region. The first region and the first impurity diffusion region are in contact with each other at a first boundary. The first region and the two second impurity diffusion regions are in contact with each other at second boundaries. The two second impurity diffusion regions sandwiching the first impurity diffusion region are provided along the gate electrode. Thus, a leak current is suppressed.
