The invention relates to a touch display device. The touch display device comprises a protective cover plate, a touch induction unit, a pressure induction unit and a display unit; the pressure induction unit comprises an upper conducting electrode layer, a lower conducting electrode layer and an elastic layer located between the upper conducting electrode layer and the lower conducting electrode layer, the upper conducting electrode layer and the lower conducting electrode layer share or are located on the same base material surface with at least one electrode in the touch induction unit and the display unit. Pressure signals of touch operation are obtained through capacitance monitoring, touch pressure signals at multiple points can be detected at the same time, as the elastic layer is introduced, the pressure induction unit can elastically deform easily under stress, and touch pressure can be detected sensitively. In addition, the conducting electrode layers forming the capacitive inductor share or are located on the same base material surface with the electrodes in the touch induction unit and the display unit, and the thickness of the whole touch display device can be reduced.
