Abstract

A touch display panel includes a first substrate, a pixel array, a second substrate, a display medium layer, a third substrate, a first touch electrode layer, a second touch electrode layer and a polarizer. The first substrate has the pixel array thereon. The second substrate is disposed opposite to the first substrate. The display medium layer is between the first substrate and the second substrate. The third substrate is disposed opposite to the second substrate and has the first touch electrode layer thereon. The second touch electrode layer is disposed between the first touch electrode layer and the second substrate. The polarizer is disposed between the first touch electrode layer and the second touch electrode layer.

Claims
