A display panel may include a detection line overlapped with a non-display region, detection pads connected to the detection line, and an input line connecting an input pad of the detection pads to the detection line. The detection line may include a first portion, which is provided at a level different from a level of the input line and includes an end connected to the input line through a first contact hole in a first contact region, and a second portion, which is provided at a level different from the level of the first portion and is connected to the first portion through a second contact hole in a second contact region. A distance between the first and second portions in a non-contact region may be less than a distance between the first contact hole and the second portion.
