Abstract
A touch display device for preventing light leakage is provided, including a display module, a first adhesive layer, a touch sensing film, and at least one protective layer. The display module includes an upper surface, a side surface, and a lower surface. The first adhesive layer is disposed on the upper surface of the display module and is bent and extends along the side surface to the lower surface, and the touch sensing film is disposed on the first adhesive layer. The at least one protective layer is disposed on one side of the touch sensing film relative to the side surface and the lower surface of the display module. At least one of the first adhesive layer disposed on the side surface of the display module or the protective layer is an opaque material, so the thickness of the device can be reduced.
