A display panel may have a first region and a second region encircled by the first region. The display panel may include first substrate, second substrate, sealant, conductive layer, and display medium layer. The first substrate may have a first recess in the first region. The second substrate may be disposed opposite to the first substrate. The sealant may be disposed between the first and second substrates, and may be received by the first recess. The conductive layer may be disposed on the first substrate, cover the first recess in a conformal manner, and be interposed between the first substrate and the sealant. The display medium layer may be disposed between the first and second substrates and may be encircled by the sealant. A thickness of the sealant may be larger than a distance between the first substrate and the second substrate in the second region.
