1. A display panel, divided into a display area and a non-display area, the display panel comprising:
a first substrate;
a second substrate, disposed corresponding to the first substrate; and
a sealant, arranged between the first substrate and the second substrate, and arranged in the non-display area;
wherein the first substrate comprises a first metal layer and a second metal layer that are arranged in sequence corresponding to the non-display area, and that are insulated from each other; wherein the first substrate further comprises a first insulating layer that is disposed between the first metal layer and the second metal layer and that is configured to insulate the first metal layer and the second metal layer from each other;
wherein the first metal layer comprises a first metal wire group, and the second metal layer comprises a second metal wire group; the first metal wire group comprises at least one sub-wire, the second metal wire group comprises at least one sub-connection wire; the at least one sub-wire of the first metal wire group and the at least one sub-connection wire of the second metal wire group are connected in one-to-one correspondence through a set of bridging structures, wherein the set of bridging structures comprises at least one bridging structure and are disposed within an outer edge of the sealant;
wherein a side of the sealant adjacent to the display area is an inner side of the sealant, and a side of the sealant far away from the display area is an outer side of the sealant;
wherein the set bridging structures are each disposed on a side of the outer edge of the sealant adjacent to the display area;
wherein of the set of bridging structures, a bridging structure closest to the outer edge of the sealant is an outermost bridging structure, and wherein a distance separating the outermost bridging structure from the outer edge of the sealant is at least 50 um;
wherein the second metal wire group further comprises at least one branch wire;
wherein the set of bridging structures comprises at least one direct-connecting bridging structure and at least one transition bridging structure;
wherein the at least one direct-connecting bridging structure is disposed on a respective sub-connection wire, and directly connects a respective sub-wire with the respective sub-connection wire;
wherein the at least one transition bridging structure is arranged on the at least one branch wire in one-to-one correspondence, and connects a respective branch wire with a respective sub-wire; wherein each of the at least one branch wire is connected to a respective sub-connection wire; and wherein a number of the at least one transition bridging structure is equal to a number of the at least one branch wire;
wherein a routing direction of each of the at least one branch wire is not parallel to a routing direction of the respective sub-connection wire, and wherein each of the at least one branch wire and the respective sub-connection wire are arranged in a same layer and are connected to each other;
wherein a distance between the at least one direct-connecting bridging structure and the outer edge of the sealant is at least 60 um, and wherein a distance between the at least one transition bridging structure and the outer edge of the sealant is at least 60 um;
wherein the outermost bridging structure is the transition bridging structure, and the sub-wire closest to the outer edge of the sealant is a first sub-wire.
