Claim 10:
11. The display panel according to claim/l, wherein:
at least one of the plurality of sub-pixels further comprises a pixel driving circuit comprising:
a first active layer located on one side of the base substrate close to the anode,
a first gate located on one side of the first active layer away from the base substrate,
an interlayer insulating layer located on one side of the first gate away from the base substrate and covering the first gate, and
a first electrode and a second electrode which are located on one side of the interlayer insulating layer away from the base substrate and electrically connected to the first active layer;
the first planarization layer is located on one side of the interlayer insulating layer away from the base substrate, and further comprises a sixth opening located at the display area;
the second planarization layer further comprises a fourth planarization portion spaced apart from the second planarization portion, located on one side of the second planarization portion away from the third planarization portion, and comprising a seventh opening located at the display area, wherein the anode is partially located in the seventh opening, and a maximum thickness of a portion of the second planarization portion in contact with the first planarization layer is smaller than a maximum thickness of a portion of the fourth planarization portion in contact with the first planarization layer; and
the display panel further comprises a fourth conductive portion located in the sixth opening and in contact with the first electrode.
