Abstract
A reflective structure for optical touch sensing, which includes a transparent substrate, a plurality of microstructures and a transmittive reflective layer. The transparent substrate has a surface. The microstructures are disposed on the transparent substrate and expose a portion of the surface to allow a visible light to pass through. The transmittive reflective layer is disposed on the microstructures and at least covers a portion of the microstructures.
