Abstract: The display device includes a display panel where sub-pixels are disposed. The display device includes a data driver that supplies a data voltage to the sub-pixels via data lines. The sub-pixels includes first sub-pixels to third sub-pixels . The first sub-pixels and second sub-pixels are alternately disposed on odd-numbered columns and the third sub-pixels are disposed on even-numbered columns. Each of the data lines branches into sub-data lines through a MUX, and the sub-data lines are disposed on both sides of the sub-pixels disposed on a column. Any one third sub-pixel of the third sub-pixels disposed on a row is connected to a sub-data line disposed on one side of the any one of third sub-pixel. Further, another third sub-pixel adjacent to any one third sub-pixel disposed on the row is connected to a sub-data line disposed on another side of the adjacent third sub-pixel. Thus, line dim is reduced.
