Abstract: A display apparatus includes a display panel, a driving controller, a gate driver and a data driver. The driving controller is configured to insert a compensation image to first image data including a normal image to generate second image data. The gate driver is configured to shift an output time of a gate signal and to output the gate signal having a shifted output time to the display panel. The data driver is configured to generate a data voltage based on the second image data and to output the data voltage to the display panel. A gate shift amount when the compensation image is applied is substantially the same as a gate shift amount immediately before the compensation image is applied.
