Optionally, referring to fig. 1 and fig. 2, the display panel further includes a display area 12 located on a side of the bending area 11 away from the binding area 13, and the bending area 11 includes a first side L1 and a second side L2 that are parallel to each other; the first side L1 is connected with the display area 12, and the second side L2 is connected with the binding area 13; in a direction from the first side L1 to the second side L2, the length of the bending zone 11 in a direction parallel to the first side L1 gradually decreases. As shown in fig. 2, the length of the bending region 11 in the direction parallel to the first side L1 and the second side L2 gradually decreases from the first side L1 to the second side L2, for example, the bending region 11 may be configured as a trapezoid structure, or other irregular gradual structure. Referring to fig. 2, alternatively, a portion of the cross section of the closed structure a between the through groove 111 of the bending region 11 and the binding region 13 is formed, and the length of the bending region 11 in a direction parallel to the first side L1 is gradually reduced, so that the portion between the through groove 111 of the bending region 11 and the second side L2 can be bent to form the closed structure a. Alternatively, the length of the second side L2 is less than or equal to the extension of the through groove 111, and the second side L2 can penetrate into the through groove 111, so that the portion between the through groove 111 and the second side L2 of the bending region 11 forms a bending portion with a cross-sectional shape perpendicular to the bending axis O and the above-mentioned closed structure a. Illustratively, as shown in fig. 2, the bending region 11 is bent in the direction r about a bending axis O, so that the portion between the through groove 111 and the second side L2 forms the above-mentioned closed structure a.

A plurality of signal lines for transmitting signals such as driving signals and data signals are arranged in the bending region 11, and all the signal lines extend from the first side L1 to the second side L2 of the bending region 11, because the through groove 111 is a through hole structure penetrating through the bending region 11 in the thickness direction, the signal lines do not pass through the setting position of the through groove 111, but are arranged around the through groove 111, optionally, the through groove 111 is arranged at the central position of the bending region 11 parallel to the first side L1, and the plurality of signal lines are equally divided into two parts and respectively arranged at two sides of the through groove 111.
Many signal lines that set up in bending zone 11 are when bending zone 11 is not the state of buckling, are close to the metal signal line that the demonstration side of display panel 1 set up, for the fracture of signal line in preventing bending zone 11, and optional, can only make enclosed construction A be close to the one side that is provided with the signal line for circular structure or arc structure, keep away from the one side that is provided with the signal line and can be other regular or irregular shapes.
