A display device includes: a substrate including a display area and a non-display area positioned around the display area and including a pad area adjacent to one side of the display area, a light emitting element disposed in the display area on the substrate, a pad portion disposed in the pad area on the substrate and including a plurality of output pads, a driving chip, and a control signal line. The driving chip includes a base portion facing the substrate, overlapping the pad area, and including dummy bump areas, an output bump area positioned between the dummy bump areas, and a data output area positioned between the dummy bump areas, a plurality of dummy bumps attached to a lower surface of the base portion and overlapping the dummy bump areas and the output bump area, respectively, a plurality of output bumps attached to the lower surface of the base portion, overlapping the output bump area, and connected in parallel to each other through transistors, and a plurality of detection bumps attached to the lower surface of the base portion, each of the detection bumps is electrically connected to the output bumps and overlapping the output bump area. The control signal line electrically connected through the transistors to the output bumps.

Display device

A display device includes: a substrate including a display area in which pixels are disposed and a non-display area; a common voltage transfer line disposed in the non-display area and transferring a common voltage to the pixels; a data output wire disposed at the non-display area and connected to a data line which transfers a data voltage to the pixels; and a sacrificial wire disposed between the common voltage transfer line and the data output wire and not connected to the data line.
