Abstract
A capacitance-type detecting device according to an embodiment of the invention includes a plurality of detecting electrodes that are provided on a sensor substrate such that capacitance is formed between adjacent electrodes. Capacitance formed in a corner detection region in which the detection sensitivity of the sensor substrate is relatively low is more than that formed in a central detection region in which the detection sensitivity is relatively high.
