Abstract
A capacitive touch display panel includes a first substrate, a second substrate, an opaque pattern, a plurality of transparent conductive sensor pads, and a plurality of non-transparent conductive patterns. The first substrate and the second substrate are disposed oppositely. The transparent conductive sensor pads are disposed on the second substrate. The non-transparent conductive patterns are disposed on the second substrate, and the non-transparent conductive patterns and the transparent conductive sensor pads are electrically connected and overlapping. The conductivity of the non-transparent conductive patterns is higher than that of the transparent conductive sensor pads, and the non-transparent conductive patterns are corresponding to the opaque pattern.
