A touch panel includes a touch sensing layer, substrate, and a touch sensing unit between the touch sensing layer and the substrate. At least one surface of the substrate has protruded and concave stripes. The stripes are formed by etching, printing, sand blasting, or molding. The protruded and concave stripes are formed side by side and parallel. A drop height between a top of the protruded stripe and a bottom of the concave stripe is between 1 nm to 1 μm. Pitches between two adjacent concave stripes and two adjacent protruded stripes are between 1 μm to 0.1 mm, and a ratio of widths of the protruded stripe and the concave stripe is between 0.2 to 5. Interference of lights such as the Newton-Ring and highlights will be avoided by the protruded stripes and concave stripes of the substrate.
