Abstract: A touch display device includes a first substrate, a touch electrode, a dummy electrode, a first dielectric layer and an electrostatic discharge layer. The touch electrode is disposed on the first substrate; the touch electrode includes a driving electrode and a sensing electrode, wherein the driving electrode is disposed adjacent to the sensing electrode. The dummy electrode is disposed on the first substrate and adjacent to at least one of the driving electrode and the sensing electrode, and two of the dummy electrode, the driving electrode and the sensing electrode are separated from each other. The first dielectric layer is disposed on the touch electrode and the dummy electrode, and the first dielectric layer has at least one first through hole disposed corresponding to the dummy electrode. The electrostatic discharge layer is disposed on the first dielectric layer and contacts with the dummy electrode through the first through hole.

Abstract: A touch display device includes a first substrate, a first touch pattern and an insulation layer. The first touch pattern is disposed on the first substrate, and the insulation layer is disposed on the first substrate. The insulation layer and the first touch pattern are overlapped. The insulation layer includes a protection layer and a dielectric layer, and the dielectric layer is disposed between the protection layer and the first substrate. A material of the protection layer includes an oxide, and a material of the dielectric layer comprises silicon nitride or silicon oxynitride.
