1. A cutting method of a display panel, wherein the method comprises:
along a first cutting line, cutting a color-film substrate of a to-be-cut display panel; and
along a second cutting line, cutting an array substrate of the to-be-cut display panel to obtain a display panel;
wherein, in a target direction perpendicular to an edge of the to-be-cut display panel, the second cutting line is located between the first cutting line and a display region of the to-be-cut display panel, and in the target direction, a distance between the first cutting line and the second cutting line is a preset distance,
wherein the color-film substrate comprises a first edge away from a lead region, the first cutting line comprises a first sub-cutting line away from the lead region, and the step of, along the first cutting line, cutting the color-film substrate of the to-be-cut display panel comprises:
along the first sub-cutting line, cutting the first edge of the color-film substrate of the to-be-cut display panel,
wherein the color-film substrate further comprises a third edge and a fourth edge adjacent to the first edge, the first cutting line further comprises a third sub-cutting line and a fourth sub-cutting line adjacent to the first sub-cutting line, and the step of, along the first cutting line, cutting the color-film substrate of the to-be-cut display panel further comprises:
along the third sub-cutting line, cutting the third edge of the color-film substrate of the to-be-cut display panel; and
along the fourth sub-cutting line, cutting the fourth edge of the color-film substrate of the to-be-cut display panel.
