Abstract: A display panel and display device having the same are disclosed. In one aspect, the display panel includes a first substrate including a display region configured to display images and a non-display region surrounding the display region. The display panel further includes a metal pattern disposed in the non-display region, a second substrate opposing the first substrate, and a sealant disposed between and substantially sealing the first and second substrates, wherein the sealant at least partially overlaps the metal pattern. The metal pattern includes a body portion surrounding the display region and a plurality of protrusions extending from the body portion in a direction from the display region to the non-display region.
