1. A display panel, comprising:
a display region;
a fan-out region, positioned at a side of the display region, the fan-out region comprising:
a bonding terminal; and
a fan-out wire, connected to the bonding terminal, the fan-out wire comprising:
a first fan-out wire; and
a second fan-out wire, positioned at two side of the first fan-out wire, the second fan-out wire comprises a first part, a second part and a third part;
wherein the third part is connected to the bonding terminal; at least a part of the second part is bended in a direction away from the display region; and a width of at least one of the first part, the second part and the third part is larger than a width of the first fan-out wires;
wherein the bonding terminal is arranged in an array, and a distance between the bonding terminal and the display region is shorter than or equal to a distance between the display region and an outermost sub-wire of the second fan-out wire; and
wherein the first fan-out wire comprises a plurality of sub-wires, the second fan-out wire comprises a plurality of sub-wires, a spacing between first parts of the sub-wires of the second fan-out wire orderly increases along a direction from an interface between the first fan-out wire and the second fan-out wire toward a position of the first fan-out wire, a spacing between second parts of the sub-wires of the second fan-out wire remains the same, a spacing between third parts of the sub-wires of the second fan-out wire remains the same, the spacing between the second parts of the sub-wires of the second fan-out wire is equal to the spacing between the third parts of the sub-wires of the second fan-out wire, and the spacing between the third parts of the sub-wires of the second fan-out wire is equal to a spacing between the sub-wires of the first fan-out wire.
