PROBLEM TO BE SOLVED: To provide a sensor device which is capable of obtaining a satisfactory capacitance change even in the case of a faint change of a distance between electrodes, and a display device including the same.SOLUTION: The sensor apparatus 1 includes an enclosure 10, an input member 11, and a detection mechanism 12. The input member 11 is relatively movable in a Z-axis direction with respect to the enclosure 10. The detection mechanism 12 includes an elastic member 120, a support 122, and an electrode pair 125. The elastic member 120 is disposed between the enclosure 10 and the input member 11. The support 122 is provided between the enclosure 10 and the elastic member 120 and forms an air layer G between the enclosure 10 and the elastic member 120, wherein the air layer G has a thickness changed by elastic deformation of the elastic member 120. The electrode pair 125 forms a plurality of capacitances including a capacitance component changed in accordance with the change in thickness of the air layer G. The detection mechanism 12 outputs a detection signal relating to a movement amount of the input member 11 in the Z-axis direction on the basis of the change in synthetic capacitance of the electrode pair 125. |
