1. A display panel comprising:
a first substrate;
a second substrate assembled with the first substrate;
a display medium layer disposed between the first substrate and the second substrate;
a hydrophobic surface disposed on at least one of the first substrate and the second substrate, facing the display medium layer;
a sealant-contacting surface disposed on the at least one of the first substrate and the second substrate, and being less hydrophobic than the hydrophobic surface, wherein the hydrophobic surface comprises an inner portion and an outer portion sandwiching the sealant-contacting surface;
a sealant disposed between the first substrate and the second substrate, and extending within the sealant-contacting surface;
an alignment layer disposed on the at least one of the first substrate and the second substrate and surrounded by the sealant, wherein the inner portion is defined by the alignment layer and an orthographic projection of the outer portion on the first substrate does not overlap with an orthographic projection of the alignment layer on the first substrate; and
a conductive layer disposed on the at least one of the first substrate and the second substrate and extended across the sealant to define the outer portion of the hydrophobic surface.
