Abstract
A capacitive touch panel and a touch display panel using the same are provided. The capacitive touch panel includes a substrate, a plurality of sensing structures and a light diffusing structure. Each sensing structure includes a plurality of sensing units and a plurality of bridge wires, and two adjacent sensing units are connected by a corresponding bridge wire. The light diffusing structure is formed on at least one of the bridge wires. After a light is incident to the light diffusing structure, the light is diffusely reflected.
