Abstract
A touch panel and a method for fabricating the same are presented. The method includes the following steps. A glass substrate is strengthened through a chemical method. The glass substrate includes alkali oxide. An indium tin oxide (ITO) layer is formed below the glass substrate. A sensing circuit, a driving circuit, and an interconnection circuit therebetween are formed in the ITO layer.

A touch panel, comprising:
- a glass substrate having a first surface serving as a touched surface and a second surface opposite to the first surface, strengthened through a chemical method, and comprising 60 wt % to 80 wt % silicon oxide, 1 wt % to 15 wt % aluminum oxide, and 0.1 wt % to 15 wt % alkali oxide, wherein the glass substrate has a compressive stress greater than 8 GPa measured by a 4 point-bending test;
- and
- an indium tin oxide (ITO) layer formed on the second surface of the glass substrate, wherein a sensing circuit, a driving circuit, and an interconnection circuit therebetween are formed in the ITO layer.
