Claim 0:
1. A display panel, comprising a display substrate, an opposite substrate disposed opposite to the display substrate, and a liquid crystal layer disposed between the display substrate and the opposite substrate, wherein
the display substrate comprises a display area and a peripheral area surrounding the display area;
a first base;
a plurality of pixel units located in the display area and on the first base; each of the plurality of pixel units comprises a thin film transistor and a first electrode, and in each pixel unit, a drain of the thin film transistor is electrically coupled with the first electrode through a first via hole penetrating through an interlayer insulating layer; and
an auxiliary functional layer located in the display area and on a side, away from the first base, of a layer where the first electrode is located; wherein, an orthographic projection of the auxiliary functional layer on the first base covers at least a part of an orthographic projection of the first via hole on the first base, and defines an active display area of the first electrode,
the opposite substrate comprises:
a second base; and
a second electrode located on a side of the second base proximal to the liquid crystal layer, and an orthographic projection of the second electrode on the first base covers an orthographic projection of any first electrode on the first base, and wherein
the first electrode comprises a reflective electrode, wherein
the display substrate further comprises a second signal connection line disposed in the same layer as the auxiliary functional layer and electrically coupled to the auxiliary functional layer, the second signal connection line is electrically coupled with the second electrode through a sealant; and
the second electrode is electrically coupled with the first signal connection line through the sealant.
