Abstract

A touch panel is provided. The touch panel includes a substrate, a plurality of first electrode lines, a plurality of second electrode lines and a plurality of connecting lines. The first electrode lines are disposed parallel to one another on the substrate and are respectively extended along a first direction from a first side of the substrate to a second side of the substrate opposite to the first side. The second electrode lines are disposed parallel to one another on the substrate and are respectively extended along a second direction. The first direction and the second direction are intersected with each other. The connecting lines are respectively connected to the second electrode lines. A part of the connecting lines are extended to the first side and another part of the connecting lines are extended to the second side.
