A display device has a display region for displaying controlled images. The display device includes a common electrode overlapping the display region, a data driver, a first-category common voltage electrode set including a first-category common voltage electrode that is electrically connected to the data driver and is electrically connected to the common electrode, a second-category common voltage electrode set disposed farther from the data driver than the first-category common voltage electrode set and including a second-category common voltage electrode that is electrically connected to the data driver, a third-category common voltage electrode set disposed farther from the data driver than the second-category common voltage electrode set and including a third-category common voltage electrode that is electrically connected to the common electrode, and a common voltage line overlapping the display region and electrically connected between the second-category common voltage electrode and the third-category common voltage electrode.
