Claim 0:
1. A flexible printed circuit, comprising:
an insulating base, the insulating base including a body portion and at least one first extension portion connected to an edge of the body portion, wherein
a first extension portion includes a via region, a bending region and a bonding region that are sequentially away from the body portion;
a plurality of vias are disposed in the via region, and the plurality of vias include at least one first via and at least one second via, wherein a center of an orthogonal projection of a first via on a reference plane perpendicular to a thickness direction of the insulating base is located on a first straight line parallel to a bending axis of the bending region, and a center of an orthogonal projection of a second via on the reference plane is not located on the first straight line,
a straight line where the center of the orthogonal projection of the first via on the reference plane and the center of the orthogonal projection of the second via on the reference plane are located is a second straight line; an included angle between the second straight line and the first straight line is α, α is greater than 0°, and is less than or equal to 15° (0°<α≤15°); and a distance between the first via and the second via in a direction parallel to the first straight line is greater than or equal to 1 mm;
the distance between the first via and the second via in the direction parallel to the first straight line is in a range from 1 mm to 2 mm; and
a distance between two adjacent first vias in the direction parallel to the first straight line is greater than or equal to 2 mm.
