Flexible touch panel

摘要

A flexible touch panel comprises a base material sheet; a first axis detection electrode, which is provided on the base material sheet and is patterned concerning a first axis; an insulative layer, which is provided on the first axis detection electrode; a second axis detection electrode, which is provided on the insulative layer and is patterned concerning a second axis that is perpendicular to the first axis; a first routing circuit, which electrically connects the first axis detection electrode to an external part; and a second routing circuit, which electrically connects the second axis detection electrode to an external part.

1. A flexible touch panel comprising:
a base material sheet made of insulative resin film having a first main surface; a first axis detection electrode provided on the base material sheet and patterned concerning a first axis, the first axis detection electrode having a first main surface directly contacting the first main surface of the base material sheet, a second main surface and a side surface extending between the first and second main surfaces; an insulative layer provided on the first axis detection electrode, the insulative layer directly contacting the first main surface of the base material sheet, the second main surface of the first axis detection electrode, and the side surface of the first axis detection electrode; a second axis detection electrode provided on the insulative layer and patterned concerning a second axis that is perpendicular to the first axis, the second axis detection electrode directly contacting the insulative layer; a first routing circuit electrically connecting the first axis detection electrode to an external part, the first routing circuit comprising wirings, each of the wirings having a first main surface directly contacting the first main surface of the base material sheet and a second main surface that is opposite the first main surface and faces away from the first main surface of the base material sheet; a second routing circuit electrically connecting the second axis detection electrode to the external part; and a migration prevention layer provided between the wirings of the first routing circuit and directly contacting the first main surface of the base material sheet without covering the second main surface of any of the wirings.
