For example, the second conductive layer comprises a first sub-conductive layer, a second sub-conductive layer, and a third sub-conductive layer which are sequentially arranged on the base substrate and connected in parallel; and the first sub-conductive layer is between the second sub-conductive layer and the base substrate in the direction perpendicular to the base substrate.
For example, the display panel further comprises at least one switching element, each of the at least one switching element comprises a gate electrode, a source electrode, and a drain electrode; each of the plurality of light emitting elements comprises a first electrode layer and a second electrode layer, the first sub-conductive layer is in a same layer and made of a same material as the source electrode and drain electrode, the second sub-conductive layer is in a same layer and made of a same material as the first electrode layer, and the third sub-conductive layer is in a same layer and made of a same material as the second electrode layer.
For example, the second frame region is provided with a circuit board alignment mark configured for bending the flexible circuit board, and an orthographic projection of the circuit board alignment mark on the base substrate is spaced apart from the orthographic projections of the plurality of cover plate alignment marks on the base substrate; and the orthographic projection of the circuit board alignment mark on the base substrate has a maximum size, an orthographic projection of each of the plurality of cover plate alignment marks on the base substrate has a maximum size, and the maximum size of the circuit board alignment mark is smaller than the maximum size of each of the plurality of cover plate alignment marks.
