Abstract
A digitizer includes at least one folded region and a plurality of non-folded regions. The digitizer includes: a first substrate layer; a second substrate layer disposed on the first substrate layer; a third substrate layer disposed on the second substrate layer; a first sensing line disposed between the first substrate layer and the second substrate layer; and a second sensing line substantially perpendicular to the first sensing line, disposed between the second substrate layer and the third substrate layer, and including a first sub-line portion and a second sub-line portion disposed in the non-folded region, and a third sub-line portion disposed between the first sub-line portion and the second sub-line portion and corresponding to the folded region. The third sub-line portion has a fracture strain greater than that of the first sub-line portion and the second sub-line portion.
