## Abstract

A touch display apparatus including a display panel, a touch panel, a transparent conductive layer, and a conductive adhesive layer is provided. The touch panel is disposed on the display panel, and includes a cover lens, a touch device, and a shielding conductive ring. The touch device is disposed on the cover lens and located between the display panel and the cover lens. The shielding conductive ring is disposed on the cover lens and located between the display panel and the cover lens. The shielding conductive ring surrounds the touch device. The transparent conductive layer is disposed on the display panel and located between the display panel and the touch panel. The conductive adhesive layer is disposed between the display panel and the touch panel. The shielding conductive ring is electrically connected with the transparent conductive layer through the conductive adhesive layer.
