Claim:
1. A capacitive touch panel, comprising: a substrate; and at least two transparent electrically conductive layers, wherein a first transparent electrically conductive layer includes a first plurality of electrode groups along a first direction, a second transparent electrically conductive layer including a second plurality of electrode groups along a second direction, the first plurality of electrode groups and the second plurality of electrode groups are intersected and insulated from each other, each of the electrode groups includes a plurality of electrodes in series, each of the electrode groups connects to a sensing lead at one side, at least one of the electrode groups is arranged along a direction away from the sensing lead, a suspending electrode is disposed on each of the electrodes of the electrode groups and the suspending electrodes have areas gradually decreased along the direction away from the sensing lead, and capacitances formed between the electrodes of the at least one of the electrode groups and common electrodes are reduced gradually along the direction away from the sensing lead; wherein the suspending electrode on each electrode is formed by etching an annulus-like groove on the electrode, and a region surrounded by the annulus-like groove is the suspending electrode.
