  • Publication number: 20160004344
    Abstract: A touch panel is provided. The touch panel is defined as having a viewable area and a non-viewable area. The touch panel includes a protection cover and a sensing electrode layer. The protection cover includes a strengthened substrate and a functional protection layer formed on the strengthened substrate in the viewable area. The sensing electrode layer is formed on the surface of the functional protection layer in the viewable area. The disposition of the functional protection layer prevents the sensing electrode layer from failing in a broken circuit, which occurs due to the strengthened substrate chipping or cracking. Thus, the reliability of the touch panel is enhanced. Further, a method for fabricating the touch panel is also provided.
