Abstract: A display apparatus includes a display panel including a switching element connected to a data line and a gate line, a pixel electrode connected to the switching element, a common electrode facing the pixel electrode and a liquid crystal layer disposed between the pixel electrode and the common electrode. The display apparatus further includes a data driving circuit configured to convert image data to a data voltage. The display apparatus further includes a driving voltage generator configured to generate a common voltage, in response to a voltage control signal from a timing controller, to the common electrode and the data driving circuit, which is configured to output the common voltage to the pixel electrode during an initial setting period when power is turned on to the display apparatus.
