TOUCH SCREEN, TOUCH PANEL, AND DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a large-sized touch panel of PCT system using metallic wires as wires for detection and capable of improving sensitivity in capacity detection by increasing wiring density without increasing parasitic capacity between the wires for detection.

SOLUTION: Each detection column wire 2 includes one set of the first metallic wire 2a having a zigzag pattern constituted by arranging first inclined parts 2aS inclined obliquely at an angle of inclination of 45°to the direction of column (y) and first parallel parts 2aP linked to the first inclined parts 2aS and being parallel with the direction of column (y) repeatedly in a zigzag manner along the direction of column (y) and the second metallic wire 2b having a configuration being line-symmetric to the first metallic wire 2a by using the direction of column (y) as an axis. Each row wire 3 for detection has similar structure. An inclined part 2aS1 in the first inclined part 2aS of the first metallic wire 2a and an inclined part 3aS1 in the second inclined part 3aS of the third metallic wire 3a cross orthogonally and three-dimensionally at middle points always. The other parts also have similar orthogonally crossing relationship.
