Abstract: A display device includes a display panel and a heat radiation sheet disposed under the display panel, where a first region and a second region disposed outside the first region when viewed in a thickness direction thereof are defined in the heat radiation sheet. The heat radiation sheet includes a heat radiation layer disposed in the first region, a lower protective layer disposed under the heat radiation layer, where a plurality of openings is defined in the lower protective layer, and an upper protective layer disposed above the heat radiation layer and coupled to the lower protective layer in the second region.

Abstract: A display device includes a display panel which includes a pixel including a driving transistor and a light-emitting element, and a sensing line connected to the pixel. A sensing driver senses a first sensing signal corresponding to mobility of the driving transistor through the sensing line, and processes the first sensing signal to output first sensing data. A driving controller receives the first sensing data from the sensing driver, generates mobility compensation data and kickback compensation data based on the first sensing data, and converts image data into compensation image data by the mobility compensation data and the kickback compensation data. A data driver converts the compensation image data into a data signal and provides the data signal to the pixel.
