Abstract: A display device may include: a first pixel including first and second sub-pixels coupled to first and second data lines; a data driver which supplies data signals to first and second output lines; and a switch unit which distributes the data signals to the first and the second data lines. The first and the second sub-pixels are line-symmetrical with each other. Each of the first and the second sub-pixels may include: an OLED; a first transistor which controls a driving current flowing from a first power supply to a second power supply via the OLED, in response to a voltage supplied to a node connected thereto; emission control transistors which are turned on when an emission control signal is supplied; and a reference transistor which couples a shielding layer overlapping a corresponding data line to the first power supply when the emission control signal is supplied thereto.
