Abstract: A display device includes a display panel and the display panel includes a pixel. The pixel includes a light emitting unit including at least one light emitting element, a driving transistor providing a driving current corresponding to a data signal to the light emitting unit, and a first transistor electrically connected between both ends of the light emitting unit. A driver provides the data signal to the pixel and provides a duty control signal to the first transistor. The driver varies a voltage level of the data signal in a first grayscale section in which a grayscale corresponding to the data signal is greater than or equal to a reference grayscale, and varies a duty ratio of the duty control signal in a second grayscale section in which the grayscale is less than the reference grayscale.

Abstract: A display device includes a plurality of pixels on a substrate. Each of the pixels includes a first electrode and a second electrode spaced apart from each other on the substrate, and a plurality of light emitting elements, each including a first end portion connected to the first electrode and a second end portion connected to the second electrode. The first electrode includes a plurality of first holes adjacent to the first end portion of each of the light emitting elements.
