In the display panel of this embodiment, the routing manner of the repair line is changed, so that the display panel includes a trunk line 211 and a plurality of branch lines 212, the branch lines 212 are electrically connected with the trunk line 211, meanwhile, the branch lines 212 include an extension portion and a conducting bit 30, the data line 11 intersects with the extension portion, the conducting bit 30 is located at the intersection, the conducting bit 30 can conduct the data line 11 and the repair line 21, and the cutting bit 40 is located at the corresponding position of the conducting bit 30 on the trunk line 211. By the arrangement, the vertical distance between the conducting bit 30 and the display area 10 is different from the vertical distance between the cutting bit 40 and the display area 10, and because the extending directions of the extending parts of the first half screen and the second half screen are opposite, an operator does not need to judge whether the first half screen or the second half screen is directly conducted at the conducting bit 30, and the cutting bit 40 corresponding to the conducting bit 30 is cut off.
According to the above technical solution, the vertical distance between the conducting bit 30 and the display area 10 is different from the distance between the cutting bit 40 and the display area 10 along the direction perpendicular to the plane of the display area 10.
Referring to FIG. 3, in some embodiments, the vertical distance between the on bit 30 and the display area 10 is D 1 The vertical distance between the cut-off position 40 and the display area 10 is D 2 Above the display area 10, D 1 ＞D 2 Below the display area 10, D 1 ＜D 2 。

For the arrangement of the branch lines 212, the branch lines 212 are plural, and the plural branch lines 212 are arranged side by side at equal intervals. Each of the branch lines 212 crosses each of the data lines 11, and in the case where a disconnection does not occur in the data line 11, the branch line 212 is not electrically connected to the data line 11, and in the case where a disconnection occurs, the branch line 212 is electrically connected to one end of the data line 11 to transmit a signal to the other end of the data line 11 through the branch line 212 and the trunk line 211.

The first wires 2121, the second wires 2122, and the vertical positional relationship between the first wires 2121 and the data wires 11 and between the second wires 2122 and the branch wires 212 greatly reduce the complexity of wiring, so that the wiring mode is clear, and the interference preventing capability is strong.
In some embodiments, the peripheral lead region 20 further includes a signal amplifying circuit having one end connected to the signal input terminal of the data line 11 and the other end electrically connected to the repair line 21. The amplifying circuit is used for amplifying a signal provided by a source driver IC (integrated circuit), so as to ensure that the signal has enough energy to reach the data line 11 through the repair line 21.

It will be understood that the spatially relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "above" or "over" other devices or structures would then be oriented "below" or "beneath" the other devices or structures. Thus, the exemplary term "above … …" may include both orientations of "above … …" and "below … …". The device may also be positioned in other different ways (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
The foregoing is merely a specific embodiment of the application to enable one skilled in the art to understand or practice the application. Many modifications and variations to these embodiments will be apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application are intended to be included within the scope of the present application. Thus, the present application is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
