Touch panel including a layered structure with first and second mesh terminal layers directly overlaid on each other and touch panel production method

A touch panel comprising:

• a substrate;
• a layered structure formed in a sensing region defined on one side of the substrate, the layered structure including at least a first conductor layer made of a first hardened conductive ink, a second conductor layer made of a second hardened conductive ink and an insulating layer disposed therebetween;
• and
• an external connection terminal formed outside the sensing region on the one side of the substrate;
• wherein the external connection terminal comprises a first terminal layer made of the first hardened conductive ink and a second terminal layer made of the second hardened conductive ink, such that the first terminal layer and the second terminal layer are directly overlaid on each other at a most terminal end of a conductive path of the touch panel;
• wherein the first terminal layer forms a first mesh of fine lines and the second terminal layer forms a second mesh of fine lines;
• wherein each of the first mesh of fine lines and the second mesh of fine lines has a grid pattern having a pair of periodicity directions and a pair of grid periods corresponding thereto, such that the first mesh of fine lines and the second mesh of fine lines are identical to each other in terms of the pair of periodicity directions and the pair of grid periods;
• and
• the first mesh of fine lines and the second mesh of fine lines are overlaid on each other in such a way that the first mesh of fine lines and the second mesh of fine lines are deviated from each other in both of the pair of periodicity directions, respectively by from ¼ to ¾, inclusive, of the grid period corresponding to the periodicity direction.
