Abstract

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.

Dependent claims

A display device, comprising a display panel including a display region and a non-display region enclosing the display region, when viewed in a plan view,

wherein the display panel comprises:
a detection line overlapped with the non-display region;
detection pads connected to the detection line;
and
a signal line connecting the detection pads to the detection line,
wherein the detection line comprises:
a first line portion provided at a level different from a level of the signal line, the first line portion including an end portion, which is connected to the signal line through a first interconnection contact hole in a first contact region;
and
a second line portion provided at a level different from the level of the first line portion,
wherein, when viewed in the plan view, the first line portion is provided closer to the display region than the second line portion, and
