Disclosed is a touch display device with tactile feedback function, including a first substrate (10), a second substrate (20), a liquid crystal layer (30), a patterned conductive layer (50) and an insulation layer (40); the patterned conductive layer (50) comprises a plurality of first signal lines (1) which are separately arranged in parallel and extended along a horizontal direction, and a plurality of second signal lines (2) which are separately arranged in parallel, and extended along a vertical direction, and insulated with the first signal lines (1); a side of the second substrate (20) close to the liquid crystal layer (30) includes a plurality of third signal lines (3) which are separately arranged in parallel along the vertical direction; the touch scan is achieved with the first and the third signal lines (1, 3), and the tactile feedback is achieved with the first and the second signal lines (1, 2).
