Display device for touch sensing and 3-dimensional image display, and driving method thereof

The invention provides a display device and a driving method thereof. A touch barrier panel having a touch sensing capability and a 3-dimensional image display capability is disposed on a display panel such that manufacturing cost may be reduced and the thickness thereof is relatively thin. Also, the negative liquid crystal that is not affected by the vertical electric field is used such that a mode change speed and response speed may be improved.
