Abstract
A touch input device capable of detecting a pressure of a touch on a touch surface may be provided that includes: a display panel; and an electrode disposed under the display panel. When a pressure is applied to the touch surface, a distance between the electrode and a reference potential layer is changed. A capacitance which is detected at the electrode is changed according to the distance change. The display panel includes a first area and a second area. Under a same distance change condition, a capacitance change amount detected at the electrode disposed under the second area is greater than a capacitance change amount detected at the electrode disposed under the first area.
