A display device includes the following components: multiple pixels individually arranged in each crossing region of multiple gate lines and multiple data lines; multiple dummy pixels individually connected to a dummy gate line, the multiple data lines, and a dummy data line; a gate driver driving the multiple gate lines and the dummy gate line; a data driver driving the multiple data lines and the dummy data line; a timing controller controlling the gate driver to drive the dummy gate line during a test mode, and providing test data for the data driver; a kickback detector outputting a kickback signal corresponding to the difference between the test data from the timing controller and a kickback voltage of the dummy pixels during a test mode; and a voltage generator adjusting the level of a common voltage according to the kickback signal and outputting the common voltage. First dummy pixels among the multiple dummy pixels are successively arranged in an extending direction of the multiple gate lines, and second dummy pixels are successively arranged in an extending direction of the multiple data lines.
