    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.

    Abstract: There is provided a display device including a substrate, a circuit layer, and an element layer. A display area of the substrate includes a main display area in which emission areas are arranged side by side, and at least one sub-display area surrounded by the main display area. The at least one sub-display area further includes light transmission areas located between the emission areas. The circuit layer includes light-emitting pixel drivers respectively electrically connected to the light-emitting elements of the element layer, data lines transmitting data signals to the light-emitting pixel drivers, first dummy lines extending in a first direction intersecting the data lines, and second dummy lines extending parallel to the data lines and paired with the data lines, respectively. The second dummy lines include reset transmission lines extending from the non-display area to the at least one sub-display area.
