Claim Text:
1. A flexible device having a first area and a second area, wherein a stiffness of a portion of the first area is greater than a stiffness of the second area, the flexible device comprising: a flexible substrate comprising a first surface and a second surface opposite to each other, and the second surface of the flexible substrate has a coarse structure in the first area, such that a surface roughness of the second surface in the first area is greater than a surface roughness of the second surface in the second area; and a rigid element disposed on the first surface of the flexible substrate and located in the first area, wherein a stiffness of the rigid element is greater than a stiffness of the flexible substrate and a projection area of the coarse structure on the flexible substrate overlaps an area of the rigid element.
