Abstract: A display device includes a display panel including pixels, a data driver which applies a dithering data voltage to the display panel, and a driving controller which determines whether to perform a dithering operation of applying the dithering data voltage to the display panel based on input image data. The display device alternately changes the dithering data voltage in units of one frame when the dithering operation is performed at a first dithering frequency or a third dithering frequency, and alternately changes the dithering data voltage in units of N frames when the dithering operation is performed at a second dithering frequency.

Abstract: A display device includes a display panel including a front surface at which an image is displayed and a rear surface which is opposite to the front surface; a circuit board connected to the display panel and facing the rear surface of the display panel; and a heat dissipation layer between the rear surface of the display panel and the circuit board. The heat dissipation layer includes a first heat dissipation sheet electrically connected to the circuit board and a second heat dissipation sheet spaced apart from the first heat dissipation sheet in a direction along the display panel.
