Abstract: A display device includes a substrate including a display area and a peripheral area, a pixel area, a data driver, a data divider, and coupling lines that couple the data driver to the data divider. The pixel area includes first pixel lines in a first area of the display area and coupled to first area data lines, and second pixel lines disposed in a second area of the display area and coupled to second area data lines. The data driver outputs data signals corresponding to the first and second pixel lines. The data divider includes first selectors that transfer the data signals corresponding to the first pixel lines to the first area data lines, and second selectors that transfer the data signals corresponding to the second pixel lines to the second area data lines. A distance between adjacent second selectors is shorter than a distance between adjacent first selectors.
