Abstract: A display device includes: a display panel including pixels; a scan driver which supplies a scan signal to scan lines connected to the pixels and supplies a sensing signal to sensing lines connected to the pixels; a data driver which supplies a data signal corresponding to image data to data lines connected to the pixels; a sensing part which senses a threshold voltage of a first transistor included in each of the pixels through receiving lines connected to the pixels, and corrects the sensed threshold voltage based on a voltage drop corresponding to at least one of an internal resistance of the data lines and an internal resistance of the receiving lines; and a timing controller which generates the image data by changing input image data based on the corrected threshold voltage.
