Abstract
A multi-touch resistive touch panel including a first substrate, a second substrate and a spacing element is provided. The spacing element is disposed between the first substrate and the second substrate. The first substrate has a first transparent electrode, two first conductive electrodes and two second conductive electrodes, wherein the first conductive electrodes are disposed at two boundaries of the first transparent electrode in parallel, and the second conductive electrode are disposed at another two boundaries of the first transparent electrode in parallel and perpendicular to the first conductive electrodes. The second substrate has many second transparent electrodes disposed on a surface of the second substrate facing the first transparent electrode and arranged in a first axial direction, and the second transparent electrodes themselves are extended in a second axial direction perpendicular to the first axial direction.
