ABSTRACT:
The invention provides a superior electrostatic capacitance detection device. An electrostatic capacitance detection device includes an M number of individual power-supply lines and an N number of individual output lines arranged in a matrix of M rows and N columns, and an electrostatic capacitance detecting element formed at the intersection thereof. The electrostatic capacitance detecting element includes a signal detection element and a signal amplifying element. The signal detection element includes a capacitance detecting electrode and a capacitance detecting dielectric layer. The signal amplifying element includes an MIS thin-film semiconductor device for signal amplification, including a gate electrode, a gate insulator, and a semiconductor layer.
