Abstract

A touch panel and a touch display panel having the same are provided. The touch panel includes a cover plate, a decoration layer, a plurality of first sensing series, a plurality of second sensing series, and a plurality of third sensing series. The cover plate has a display area and a non-display area surrounding the display area. The decoration layer is disposed on the non-display area of the cover plate. Each of the first sensing series includes a plurality of first sensing pads, a plurality of display-area first bridge lines, and a plurality of non display-area first bridge lines. The display-area first bridge lines bridge the first sensing pads located in the display area in a first direction. The non display-area first bridge lines bridge the first sensing pads located in the non-display area in the first direction, wherein the material of the non display-area first bridge lines is metal.
