Abstract
A touch panel includes: a uni-axially oriented base film; a transparent electrode pattern layer positioned on the uni-axially oriented base film; a first passivation layer formed in an edge region of the transparent electrode pattern layer and covering end portion side walls of the transparent electrode pattern layer; and a contact hole positioned on the first passivation layer and exposing the first passivation layer.
Claims11
A touch panel, comprising:
- a uni-axially oriented base film extending in an elongation direction;
- a transparent electrode pattern layer disposed on the uni-axially oriented base film;
- a first passivation layer disposed in an edge region of the transparent electrode pattern layer and covering end portion side walls of the transparent electrode pattern layer;
