Abstract

A touch display panel including a display panel and a touch panel is provided. The display panel includes a shielding pattern and a plurality of pixels separated by the shielding pattern and including multiple edge directions. The touch panel is disposed on the display panel and includes a plurality of first sensing series, a plurality of second sensing series and a plurality of dielectric patterns. Each dielectric pattern is disposed between each first sensing series and each second sensing series intersected therewith, and includes multiple edge direction non-parallel to the edge direction of the pixel.
