Abstract: A display device includes pixels. Each of the pixels includes: a first transistor including a gate electrode connected to a first node, a first electrode connected to a second node, and a second electrode connected to a third node; a second transistor including a gate electrode connected to a first scan line, a first electrode connected to a data line, and a second electrode connected to the second node; a first sub-transistor including a gate electrode connected to the first scan line, a first electrode connected to the first node, and a second electrode connected to a fourth node; and a second sub-transistor including a gate electrode connected to the first scan line, a first electrode connected to the fourth node, and a second electrode connected to the third node. A channel width of the second sub-transistor is wider than a channel width of the first sub-transistor.

Abstract: A display device includes: a display panel including a first pixel, a second pixel adjacent to one side of the first pixel, and a third pixel adjacent to the other side of the first pixel; a first scan driver supplying a first signal to the first to third pixels through a first scan line; a second scan driver supplying a second scan signal to the second and third pixels through a second scan line when a first time elapses after the supply of the first scan signal is started; a data driver supplying a data voltage to a plurality of output lines; and a data divider selectively supplying the data voltage to data lines respectively coupled to the first to third pixels. Each of the second and third pixels includes a switching transistor controlled by the second scan signal.
