  • Publication number: 20160252989
    Abstract: A touch panel and a method for fabricating the same are disclosed. The method for fabricating the touch panel forms a pattern of a protruding structure on a base substrate by using a negative photoresist material, and the pattern of the protruding structure formed thereon is a pattern having a cross section which gradually increases from the base substrate to the outside surface and is similar to an inverted trapezoidal. Thereafter patterns of a touch electrode and dummy electrode insulated from each other are formed by using the pattern of the formed protruding structure as a mask. As the pattern of the touch electrode and the dummy electrode are disconnected through level difference of the protruding structure, the patterns of the touch electrode and the dummy electrode overlay the whole base substrate from the top view, allowing the whole surface of the touch panel to have the same optical property.
