A display device includes a substrate including an active region, a non-active region disposed outside the active region, and a driving region disposed on one side of the non-active region, gate lines disposed in the active region to extend in a row direction, data lines disposed in the active region to extend in a column direction, pixels connected to the gate lines and the data lines, repair wiring disposed in the non-active region, and a gate driving integrated circuit (“IC”) disposed in the driving region, the gate driving IC generating gate driving signals and transmitting the gate driving signals to the gate lines, where the repair wiring includes a first sub-repair line connected to the gate driving IC, and a second sub-repair line disposed in the non-active region to extend in the column direction, to be connected to the first sub-repair line, and to overlap the gate lines.
