Abstract: A display device includes a display panel including a display area including sub-pixels, a data driver providing a data voltage to each of the sub-pixels through a data line, a gate driver providing a bias gate signal to each of the sub-pixels and a driving controller compensating for the data voltage written in a second area to which the bias gate signal having an activation level in a first period in which the data voltage is written in the first area is applied based on a first data voltage corresponding to a grayscale of a first area of the display area and a second data voltage corresponding to a grayscale of a different area from the first area of the display area.
