Abstract: A touch display device includes a reflective display module, a touch sensing layer, a light guide member, a ground shielding layer, and a first adhesive layer. The touch sensing layer is disposed on a display surface of the reflective display module, and the light guide member is disposed between the reflective display module and the touch sensing layer. The ground shielding layer is in contact with the light guide member and located between the light guide member and the touch sensing layer. The ground shielding layer electrically connects to one of the reflective display module and the touch sensing layer to electrically connect to a ground potential through the one of the reflective display module and the touch sensing layer. The first adhesive layer is disposed between the light guide member and the reflective display module, and is located between the ground shielding layer and the reflective display module.

Abstract: A touch display device includes a substrate, a display element layer, a composite substrate, a touch electrode and an adhesive layer. The display element layer is disposed on the substrate. The composite substrate includes a support layer and a moisture barrier layer. The moisture barrier layer is in direct contact with and covers a surface of the support layer. The display element layer is located between the substrate and the composite substrate. A moisture transmission rate of the moisture barrier layer is less than 1×10−2 g/m2/day. The touch electrode is disposed on the composite substrate. The adhesive layer is disposed between the display element layer and the composite substrate.

Abstract: A touch display device includes a driving substrate, a display medium layer, a common electrode layer, a touch electrode layer, and a protective layer. The display medium layer is disposed on the driving substrate. The common electrode layer is in direct contact with and disposed on the display medium layer. The common electrode layer includes multiple common electrodes, and two adjacent of the common electrodes have a spacing between each other. The touch electrode layer is disposed on the display medium layer. The touch electrode layer and the common electrode layer define a touch structure layer. The protective layer is disposed on the touch electrode layer.
