Abstract
A pixel of a display device may pre-charge a light emitting element in non-emission periods immediately before emission periods by varying a voltage level of an initialization voltage. As a result, a luminance non-uniformity phenomenon that may occur as the result of a deterioration deviation of the light emitting element may be removed or reduced.
