1. A display panel, comprising:
a base substrate; and
a plurality of sub-pixels, disposed on the base substrate, at least one of the plurality of sub-pixels comprising a reflective electrode;
wherein the reflective electrode comprises at least a first reflective electrode and a second reflective electrode insulated and spaced apart from each other, the first reflective electrode is provided with a first through hole, the second reflective electrode is provided with a second through hole;
wherein the base substrate has a first partition and a second partition, an orthographic projection of the first reflective electrode on the base substrate is located in the first partition, and an orthographic projection of the second reflective electrode on the base substrate is located in the second partition; and
the display panel further comprises:
an opposite substrate, disposed opposite to the base substrate; and
a color resist layer, located between the base substrate and the opposite substrate, and comprising a sub-color resist layer located in each sub-pixel;
wherein the sub-color resist layer comprises a first sub-color resist region and a second sub-color resist region, and in a direction perpendicular to a plane where the base substrate is located, the first partition covers the first sub-color resist region, and the second partition covers the second sub-color resist region;
wherein the sub-color resist layer located in the first partition is provided with a first via hole, and the first via hole penetrates through the sub-color resist layer; and
an orthographic projection of the first via hole on the base substrate and an orthographic projection of the first through hole on the base substrate do not overlap.
