Change circuit unit.
Meanwhile, sensing electrode has a structure in which, in the structure shown here, sensing electrode is generally arranged at both direction (example
Such as, vertical and horizontal direction) on detect apply touch stimulate coordinate.
However, when touch electrode is formed with convex shape (embossed shape) on the substrate of contact panel, depositing
In following problem.Firstly, since sensing electrode is protruded with its thickness, so increased the integral thickness of product.Second, by all
Technique such as cleaning may frequently occur crackle.
In order to form sensing electrode, after the conductive material of such as ITO is coated on the front surface of substrate, it should go
Except the conductive material being present in the region in addition to wherein by the region of formation sensing electrode.Therefore, increased material into
This.Further, since increased single technique, so reducing productivity ratio, and fraction defective is increased.
If forming the sensing electrode for extending in different directions at one of single substrate simultaneously on the surface, can not keep away
Produce intersection region with exempting from, and sensing electrode should be electrically insulated from each other in intersection region.Therefore, technique becomes complicated.
