A display apparatus includes a display panel, a gate driver, a data driver and a driving controller. The display panel displays an image based on input image data. The gate driver outputs a gate signal to a gate line of the display panel. The data driver outputs a data voltage to a data line of the display panel. The driving controller controls operations of the gate driver and the data driver and drive a still image display area and a video image display area of a display area of the display panel in different driving frequencies. The driving controller includes a still image determiner which divides the input image data into a plurality of still image determining blocks, respectively determines whether the still image determining blocks represent a still image or a video image and determines a boundary between the still image display area and the video image display area.
