A touch display device includes a touch sensing unit, a first conductive adhesive layer, a second conductive adhesive layer, a flexible printed circuit board, a liquid crystal display unit, a first adhesion layer and a second adhesion layer. The first adhesion layer serves to adhere the touch sensing unit to the liquid crystal display unit. The touch sensing unit includes a transparent substrate, multiple first sensing electrodes and multiple second sensing electrodes. The transparent substrate has a touch section and a peripheral section around the touch section. The first sensing electrodes are disposed on one side of the transparent substrate and positioned on the touch section. The second sensing electrodes are disposed in the liquid crystal display unit. The touch display device increases the ratio of good products and lowers the manufacturing risk.
