Claim:
1. A display panel, comprising: a first substrate comprising a display area and a non-display area, and the first substrate having a first edge and a second edge, wherein the first edge is adjacent to the second edge; a sealant disposed on the first substrate and on the non-display area; and a planarization layer disposed on the first substrate and comprising a plurality of openings on the non-display area, wherein the plurality of openings are formed to pass through the planarization layer, the plurality of openings comprise a first opening, a second opening and a third opening which are disposed between the first edge and the display area, and the sealant surrounds but does not overlap with the plurality of openings in the plan view, and wherein a first distance is a distance between the first opening and the first edge, a second distance is a distance between the second opening and the first edge, and a third distance is a distance between the third opening and the first edge, wherein the third distance is different from the first distance and the second distance, wherein a fourth distance is a distance between the first opening and the second edge, a fifth distance is a distance between the second opening and the second edge, and a sixth distance is a distance between the third opening and the second edge, wherein the sixth distance is greater than the fourth distance and less than the fifth distance, wherein the display panel further comprises a metal layer disposed on the first substrate, a partial surface of the metal layer exposed through the first opening has a first roughness, another partial surface of the metal layer disposed under the planarization layer has a second roughness, and the first roughness is greater than the second roughness, and wherein the display panel further comprising a transparent conductive layer disposed on the first substrate, wherein the transparent conductive layer is formed on the partial surface of the metal layer exposed through the first opening.
