Abstract
A capacitive touch panel is disclosed. The capacitive touch panel includes a substrate having a plurality of sensing units, a frame having a hollow opening for accommodating the substrate, and an optical composite layer disposed on the frame. Two adjacent sensing units comprise a distance therebetween. the frame and the substrate form a composite structure. The optical composite layer includes a shielding layer and an ink layer, and the thickness of the shielding layer is adjusted with respect to the distance such that the sensing units are invisible from outside.
