Touch sensor panel

A touch sensor panel comprising:

• a base layer comprising a first side and a second side, wherein the base layer is a cyclo-olefin polymer (COP) layer;
• a first adhesive layer having a first side and a second side, wherein one of the first and the second sides of the first adhesive layer is bonded to one of the first and the second sides of the base layer and wherein the first adhesive layer is composed of a pressure-sensitive adhesive (PSA);
• an electrode layer having a first side and a second side, wherein one of the first and the second sides of the electrode layer is bonded to the other of the first and the second sides of the first adhesive layer;
• a second adhesive layer having a first side and a second side, wherein one of the first and the second sides of the second adhesive layer is bonded to the other of the first and the second sides of the electrode layer and wherein the second adhesive layer is composed of a pressure-sensitive adhesive (PSA);
• and
• a functional layer having a first side and a second side, wherein one of the first and the second sides of the functional layer is bonded to the other of the first and the second sides of the second adhesive layer, wherein the functional layer is a polarization layer,
• wherein the first and the second adhesive layers have a modulus of 1 to 2 MPa and a thickness of 20 to 30 μm, thereby minimizing the occurrence of cracks in the electrode layer while maximizing the dynamic folding capability of the touch sensor panel.
