Abstract: A display device includes a first active pattern disposed on a substrate, a first gate electrode disposed on the first active pattern, a second active pattern disposed on the first gate electrode, being electrically connected to the first gate electrode, and including an extension part extending in a first direction and a protrusion part protruding from the extension part in a second direction crossing the first direction, and a voltage line disposed on the second active pattern, extending in the first direction, and overlapping the protrusion part in an overlapping region. The voltage line contacts the protrusion part through a first contact, and the first contact entirely overlaps the overlapping region on a plane.

Abstract: A display device includes a substrate including a display area and a peripheral area, an inspection terminal in the peripheral area and configured to transmit an inspection signal to the display area, an inspection wiring that connects the display area to the inspection terminal, a semiconductor resistor connected to each of the inspection terminal and the inspection wiring, an insulating film, and a planarization layer including a terminal opening. The planarization layer covers at least one end of the inspection terminal and the inspection terminal exposes a portion of the inspection terminal. The semiconductor resistor is below the inspection terminal, with an insulating film therebetween, and is in contact with the inspection terminal through a first contact hole defined in the insulating film. A portion of the semiconductor resistor is overlapped by the terminal opening.
