Abstract
Discussed is a touch display device able to sense a touch position of a user touch and an amount of user touching force. A case disposed below the backlight unit is used as a touching force sensing electrode, enabling a touch display device to sense touch force using the case. A gap is formed by an open area in the bottom cover of the backlight unit, enabling the user touching force to be sensed without an increase in the thickness of the touch display device.
