Abstract
A capacitive touch panel has a plurality of first conductor lines and a plurality of second conductor lines. The first conductor lines are disposed in a first direction for sensing a contact with an object. The second conductor lines are disposed in a second direction to be intersected insulatively with the first conductor lines so as to define an overlapping region at each intersection of a first conductor line and a second conductor line. As a driving signal is applied to one of the second conductor lines, the overlapping region defined at the intersection forms a capacitance. Each of the first conductor lines defines at least one opening in each of the overlapping regions.
