ABSTRACT:
Aspects of the invention provide a superior electrostatic capacitance detecting device. The electrostatic capacitance detection device can include M number of row lines, N number of column lines, and electrostatic capacitance detecting devices formed at intersections of these lines. The electrostatic capacitance detecting element can include a signal detection element, a signal amplifying element, a column selecting element, and a row selecting element, and the signal detection element can include a capacitance detecting electrode, a capacitance detecting dielectric layer, and a reference capacitor, and one electrode of the reference capacitor connects to a column line.
