A touch input device capable of detecting a pressure of a touch on a touch surface may be provided that includes a substrate and a display module. The touch input device further includes an electrode which is disposed at a position where a distance between the electrode and a reference potential layer is changed by the touch on the touch surface. The distance may be changed depending on a magnitude of a pressure of the touch. The electrode outputs an electrical signal according to the change of the distance. A spacer layer is disposed between the reference potential layer and the electrode.
