    Abstract: The present invention discloses a touch panel structure, a method for forming the same and a touch device having the same. A touch panel structure of the present invention comprises a substrate, a color layer, an inorganic layer, and a photoresist layer. The color layer is disposed on a surface of the substrate. The inorganic layer is disposed on a surface of the color layer which is opposite to the substrate. The photoresist layer is disposed on a surface of the inorganic layer which is opposite to the substrate, wherein the color layer and the photoresist layer have different surface tensions. For electronic products that rely on the Colorful OGS (One Glass Solution) technology, by providing an inorganic layer between the color layer and the photoresist layer, problems related to different surface tensions when the layers are stacked during the manufacturing process of a touch panel can be solved.
