1. A display device, comprising:
pixels;
first scan lines connected to the pixels to supply first scan signals to the pixels at a second frequency which corresponds to an image refresh rate of the pixels;
second scan lines connected to the pixels to supply second scan signals different from the first scan signals to the pixels at the second frequency; and
third scan lines connected to the pixels to supply third scan signals to the pixels at a first frequency,
wherein a pixel disposed on an i-th horizontal line of the pixels comprises:
a light emitting element including a first electrode, and a second electrode connected to a second power supply;
a first transistor including a first electrode connected to a first node electrically connected to a first power supply, and configured to control a driving current based on a voltage of a second node;
a second transistor connected between a data line and the first node, and turned on by one of the first scan signals supplied to an i-th first scan line of the first scan lines;
a third transistor connected between the second node and a third node connected to a second electrode of the first transistor, and turned on by one of the second scan signals supplied to an i-th second scan line of the second scan lines; and
a fourth transistor connected between the first node and an i-th emission control line or between the first node and a bias power source, and turned on by one of the third scan signals supplied to an i-th third scan line, and
wherein i is a natural number.
