A touch display apparatus includes a display panel, a touch electrode, a first pressure sensing electrode, a polarizer and a second pressure sensing electrode. The display panel includes a display region and a peripheral region, and displays an image. The touch electrode is disposed on the display region of the display panel, includes a plurality of touch patterns, and detects a touch position. The first pressure sensing electrode is disposed on the peripheral region of the display panel. The touch electrode and the first pressure sensing electrode are disposed in the same layer. The polarizer is disposed on the touch electrode and the first pressure sensing electrode, and includes a dielectric elastomer material. The second pressure sensing electrode is disposed on the polarizer, and overlaps the first pressure sensing electrode.
