Touch Panel Manufacturing Method

A touch panel manufacturing method comprising:

• preparing a substrate;
• forming a first sensing layer and a second sensing layer respectively on a first surface and a second surface of the substrate;
• forming a first protective layer and a second protective layer respectively on the first sensing layer and the second sensing layer;
• forming a first electrode layer with spaced electrodes and a second electrode layer with spaced electrodes by a firing process;
• and
• the first electrode layer and the second electrode layer respectively being penetrated through the first protective layer and the second protective layer and formed on a surface of the first sensing layer and a surface of the second sensing layer.

A touch panel manufacturing method comprising:

• preparing a substrate;
• sequentially forming a first sensing layer and a first protective layer on a first surface of the substrate in that order;
• forming a first electrode layer with spaced electrodes by a firing process;
• the first electrode layer being penetrated through the first protective layer and formed on a surface of the first sensing layer;
• sequentially forming a second sensing layer and a second protective layer on a second surface of the substrate in that order;
• forming a second electrode layer with spaced electrodes by a firing process;
• and
• the second electrode layer being penetrated through the second protective layer and formed on a surface of the second sensing layer.
