Display device
A display device includes a first active pattern, a first compensation gate electrode disposed on the first active pattern, including a first electrode extension part extending in a first direction and a first electrode protrusion part protruding from the first electrode extension part in a second direction crossing the first direction, and a compensation gate line disposed on the first compensation gate electrode and including a line extension part extending in the first direction and a first line protrusion part protruding from the line extension part in the second direction. The line extension part contacts the first electrode extension part through a first contact hole, wherein the first contact hole may overlap the first electrode extension part. The first line protrusion part may contact the first electrode protrusion part through a second contact hole, wherein the second contact hole may overlap the first electrode protrusion part.
