Abstract: A display device can include a substrate on which reference lines extending in a first direction are disposed; first sub pixels which include a first circuit area disposed at one side of the reference lines and a first emission area disposed at another side of the reference lines; second sub pixels which include a second emission area disposed at one side of the reference lines and a second circuit area disposed at another side of the reference lines; first data lines which extend in the first direction and are disposed to be spaced apart from the reference lines; and second data lines which extend in the first direction and are disposed to be spaced apart from the reference lines. Accordingly, the reference line and the data line are disposed at both sides of the circuit area so that the reference line and the data line do not overlap and the ripple phenomenon and the dim phenomenon can be improved.
