Abstract: A display device includes: a first pixel connected to a first scan line and a data line; a second pixel connected to a second scan line and the data line; and a data driver connected to the data line. The data driver includes: a data voltage generator which applies a data voltage corresponding to a grayscale value of the first pixel to the data line when a scan signal of a turn-on level is applied to the first scan line; and an off voltage generator which applies an off voltage corresponding to a black grayscale value to the data line when a scan signal of a turn-on level is applied to the second scan line, in a first mode.

Abstract: A pixel includes: a first transistor including a gate electrode electrically connected to a first node, a second node to which a first power voltage for driving the light emitting element is applied, and a third node electrically connected to the light emitting element; a first emission control transistor having an on-off timing controlled by a first emission control signal; and a second emission control transistor having an on-off timing controlled by a second emission control signal. A time interval exists between a time at which the first emission control signal having a turn-on level is input such that a voltage of the second node is dropped from a bias voltage having a voltage level higher than a voltage level of the first power voltage and a time at which the second emission control signal having a turn-on level is input.
