Abstract
A display device includes pixels, a scan driver, an emission driver, and a data driver. A pixel of an i-th horizontal line includes a light emitting element, a first transistor including a first electrode connected to a first node, a second transistor including a gate electrode connected to an (i+x)-th emission control line and connected to one of the data lines, a third transistor including a gate electrode connected to an (i+y)-th emission control line, and connected between the second transistor and the first node, a fourth transistor connected between a third node connected to a second electrode of the first transistor and a second node, and turned on by a scan signal supplied to an i-th scan line, and a fifth transistor connected between the first power and the first node, and turned off by the emission control signal supplied to an i-th emission control line.
