Abstract: A display device can include a plurality of sub pixels disposed on a substrate including an emission area and a non-emission area; a gate line disposed in the non-emission area, the gate line extending in a first direction; at least one signal line disposed in the non-emission area, the at least one signal line overlapping with the gate line; at least one branch line connected to the at least one signal line; and a repair part overlapping with the at least one branch line, the repair part being spaced apart from the at least one branch line. Also, the repair part can reflect laser light onto a portion of the least one branch line overlapping with the repair part and cut the least one branch line to deactivate one of the plurality of sub pixels.

Abstract: A display device includes a display panel having a plurality of pixels. The device includes a data driver configured to supply a data voltage to the plurality of pixels via a plurality of data lines using a sensing result of the plurality of pixels via a first reference voltage line, a second reference voltage line, and a third reference line. The device includes a gate driver configured to supply a gate signal to the plurality of pixels via a plurality of gate lines. Each of the plurality of data lines is branched into a plurality of sub data lines and each of the plurality of sub data lines is connected to a plurality of sub pixels having the same color. The reference voltage lines are connected to the plurality of sub pixels. The device improves a sensing speed of the sub pixel.
