Abstract: A display panel including: pixels disposed in an active area of a substrate; data lines connected to the pixels; and a crack detection line disposed in a peripheral area of the active area in the substrate. The crack detection line includes a plurality of stacked conductive layers and at least one insulating layer disposed therebetween. At least one of the conductive layers is electrically connected to any one of the data lines.

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: A display device includes: first pixels at a first pixel area and connected to first scan lines; a first scan driver to supply first scan signals to the first scan lines; second pixels at a second pixel area and connected to second scan lines; a second scan driver to supply second scan signals to the second scan lines; third pixels at a third pixel area and connected to third scan lines; and a third scan driver to supply third scan signals to the third scan lines. In a first mode, each of the first scan signals has at least a portion having a first pulse width, and each of the second scan signals has at least a portion having a second pulse width different from the first pulse width.
