Abstract: A touch input device capable of detecting a touch pressure is provided that includes: a display module having a pressure electrode which is formed on a back side of the display panel and is for detecting the pressure; and a reference potential layer which is formed separately from the pressure electrode. The touch input device detects the touch pressure on the basis of a capacitance change amount according to a change of a distance between the pressure electrode and the reference potential layer. As a result of this, the touch input device becomes thinner, has a reduced manufacturing cost thereof, and detects a touch position and touch pressure without deteriorating the visibility and optical transmittance of the display module.
