A display apparatus includes a display panel, a driving controller and a data driver. The display panel includes a pixel. The driving controller generates an age compensation value using a sensed age generated based on sensing data of the pixel and an accumulated age generated based on accumulated grayscale values of input image data, generates a final age based on the age compensation value, and compensates a grayscale value of the input image data based on a final age to generate a data signal. The data driver converts the data signal to a data voltage and outputs the data voltage to the display panel.
