The present invention relates to a display panel. The display panel includes a plurality of pixels arranged in a display region of a substrate, a plurality of data lines connected to the pixels, and a crack detection line arranged in a peripheral region of the display region of the substrate. The crack detection line includes a plurality of conductive layers stacked by interposing at least one insulating layer therebetween. At least one among the conductive layers is electrically connected to at least one among the data lines. So, damage to the display panel can be prevented.
