Claim 17:
18. A method for manufacturing a flexible circuit board, the flexible circuit board being in a non-display region of a display panel and provided with a driving circuit for driving the display panel thereon, wherein the method comprises:
providing a body portion comprising a first main body portion, a second main body portion, and a foldable portion, the foldable portion being between the first main body portion and the second main body portion; and
bending the foldable portion to fold the second main body portion such that the second main body portion overlaps the first main body portion,
the flexible circuit board comprises a first surface and a second surface opposing to each other, wherein
the first main body portion has an overlapping region and a non-overlapping region, a region where the second main body portion overlaps the first main body portion after the foldable portion is bent being the overlapping region, and a region where the second main body portion does not overlap the first main body portion after the foldable portion is bent being the non-overlapping region,
the method further comprises forming a first adhesive, a second adhesive, and a third adhesive, such that:
the first adhesive is on the second surface, corresponds to the first main body portion, and in the non-overlapping region,
the second adhesive is on the second surface, corresponds to the first main body portion, and is in the overlapping region,
the third adhesive is on the first surface, corresponds to the second main body portion, and covers the second main body portion, and
none of the first adhesive, the second adhesive and the third adhesive is on two sides of the foldable portion.
