Flexible touch screen panel and flexible display device with the same

A flexible touch screen panel, comprising:

• a thin film substrate including an active area and a non active area positioned at the outside of the active area, the thin film substrate having at least two second regions and a first region that is disposed between the two second regions adjacent to each other;
• sensing patterns formed on the active area of a first surface of the thin film substrate, and including first sensing cells arranged along a first direction and second sensing cells arranged along a second direction;
• and
• sensing lines formed on the non active area of the first surface of the thin film substrate, and electrically connected to the sensing patterns,
• wherein the flexible touch screen panel has a folding axis about which the flexible touch screen panel is bent and the folding axis is disposed in the first region,
• wherein when the flexible touch screen panel is bent about the folding axis, the first region forms a curvature and the second regions maintains a flat without a curvature,
• wherein an interval between the first and second sensing cells adjacent to each other in the first region is different from an interval between the first and second sensing cells adjacent to each other in the second regions when the flexible touch screen panel is in a non-bent state, and
• wherein the interval between the first and second sensing cells in the first region is smaller when the flexible touch screen panel is in a bent state than when the flexible touch screen panel is in a non-bent state.
