Image display device

An image display device that includes a plurality of pixel circuits, which are mounted on a substrate, formed with a thin-film transistor, and arranged in a matrix form;

• a plurality of data lines, which transmit an image signal to the plurality of pixel circuits;
• a plurality of gate lines, which intersect with the data lines and transmit a scanning pulse to the plurality of pixel circuits;
• and a drive circuit, which drives the data lines and the gate lines, the image display device comprising:
• an oscillator circuit that independently oscillates without an external synchronization signal and is formed with a thin-film transistor on the substrate;
• and
• a plurality of level shifters that are formed with a thin-film transistor;
• wherein the plurality of level shifters each have a shutdown function for reducing the power consumption of the level shifters;
• wherein the plurality of level shifters include a first level shifter and a group of second level shifters;
• wherein the shutdown function of the first level shifter is controlled by an output pulse of the oscillator circuit;
• and
• wherein the shutdown function of each second level shifter of the group of second level shifters is controlled by an output signal of the first level shifter.
