A display panel includes a substrate that comprises a bending zone and a non-bending zone. The substrate is disposed with first signal lines. The first signal lines are arranged in a first direction and extend in a second direction. The first direction intersects with the second direction. The first signal lines extend at least from the non-bending zone to the bending zone. A thickness of a portion of the first signal lines located in the bending zone is larger than a thickness of a portion of the first signal lines located in the non-bending zone; or the display panel further includes at least one auxiliary conductive portion located in the bending zone, wherein the orthographic projection of the auxiliary conductive portion on the substrate overlaps with the orthographic projection of the first signal line on the substrate.
