1. A display panel, comprising:
a base substrate comprising a display area and a peripheral area surrounding the display area, wherein the peripheral area comprises a bonding area and a non-bonding area other than the bonding area, wherein the bonding area surrounds a first edge of an edge of the display area, and the non-bonding area surrounds a second edge of the edge of the display area other than the first edge;
a separator located at the peripheral area, the separator comprising at least one separation portion at least partially surrounding the display area, each of the at least one separation portion comprising a first separation portion located at the non-bonding area and surrounding the second edge, wherein each of the at least one separation portion comprises a first separation layer and a second separation layer sequentially stacked on the base substrate, and a first orthographic projection of the first separation layer on the base substrate is within a second orthographic projection of the second separation layer on the base substrate;
a cathode comprising:
a first cathode portion located on one side of the separator close to the display area, and
a second cathode portion located on one side of the separator away from the display area and spaced apart from the first cathode portion; and
an encapsulation layer located on one side of the cathode away from the base substrate, and comprising a first inorganic layer, a second inorganic layer, and an organic layer located between the first inorganic layer and the second inorganic layer, wherein an edge of an orthographic projection of the first inorganic layer on the base substrate, an edge of an orthographic projection of the organic layer on the base substrate, and an edge of an orthographic projection of the second inorganic layer on the base substrate overlap.
