Abstract: A display device includes a display panel including pixel driving circuits and light emitting elements, a data driver that outputs data voltages to the pixel driving circuits, and a timing controller that controls the data driver. The data driver includes a first amplifier and second amplifiers. The first amplifier outputs first data voltages to a first data line connected to first pixel driving circuits arranged in a first column and output second data voltages to a second data line connected to second pixel driving circuits arranged in a second column. The second amplifiers output third data voltages to third data lines connected to third pixel driving circuits arranged in third columns which are disposed between the first column and the second column. Thus, the display device reduces the number of amplifiers included in the data driver.
