A flexible touch sensing unit includes a substrate including a plane region and a bending region, a plurality of sensing electrodes disposed on the substrate, a plurality of sensing lines surrounding the plurality of sensing electrodes and electrically connected to the plurality of sensing electrodes, and a damage prevention layer disposed in the bending region. Cracks on the sensing electrodes and the sensing lines which are disposed in the bending region may be prevented by the damage prevention layer in the bending region. A resulting flexible display device using the flexible touch sensing unit may be thinner by omission of a flexibility enhancing layer.

A flexible printed circuit board (FPCB) simultaneously coupled to both surfaces of a substrate structure, e.g., a touch screen panel is provided. The FPCB includes a main substrate unit having a first pad unit and an auxiliary substrate unit extending from the main substrate unit to one side of the first pad unit. The auxiliary substrate unit includes a first substrate unit positioned parallel with the first pad unit along a first direction, a second substrate unit including a second pad unit, the second substrate unit spaced apart from the first substrate unit in a second direction, orthogonal to the first direction, and a plurality of third substrate units extending along the second direction between the first and second substrate units.
