Abstract: A touch display device includes a display panel and a light guide board. The light guide board includes a light guide base, a touch-sensitive membrane, and a buffer layer. The touch-sensitive membrane is disposed on a first surface of the light guide base for sensing the positions of the user's fingers or other indicants. The buffer layer is arranged between the light guide base and the touch-sensitive membrane for separating said light guide base from the touch-sensitive membrane. Since the touch-sensitive membrane is disposed on the light guide base, it is not necessary to provide an additional plastic substrate to install the touch-sensitive membrane thereon. Consequently, the thickness of the touch display device can be reduced.
