Abstract: A display apparatus includes: a display panel including: a gate line; a data line; and a pixel electrically connected to the gate line and the data line, and to display a normal image and a compensation image; a gate driver to output a gate signal to the gate line; a data driver to output a data voltage to the data line; and a power voltage generator to vary a level of a gate power voltage based on a compensation duty ratio corresponding to a ratio between a display duration of the normal image and a display duration of the compensation image.
