A display panel including a display region and a sealant region is provided. The display panel includes a first and a second substrate opposite to each other, a dielectric layer, a planarization layer, a display medium and a sealant. The dielectric layer is disposed on the first substrate. The planarization layer is disposed on the dielectric layer, and has at least one opening exposing the dielectric layer. The opening is disposed at a corner of the sealant region, where a width of the opening is gradually reduced as away from the corner. The display medium and the sealant are respectively disposed in the display and the sealant region between the first and the second substrate. The sealant is filled in a part of the opening without covering at least a sidewall of the opening of the planarization layer, and contacts the dielectric layer through the opening.
