A switchable touch stereoscopic image device includes a stereoscopic image generating module and a touch sensing module. The stereoscopic image generating module includes a first substrate, a second substrate, a light-path converting layer, driving electrodes and a common electrode. The first and second substrates are disposed corresponding to each other. The first substrate has a top surface. The second substrate has a top surface and a bottom surface facing the top surface of the first substrate. The light-path converting layer is disposed between the first and second substrates. The driving electrodes are disposed on the top surface of the first substrate. The common electrode is disposed on the bottom surface of the second substrate. The touch sensing module is disposed on a side of the second substrate of the stereoscopic image generating module and includes sensing electrodes disposed on a side of the top surface of the second substrate.
