Disclosed is a sensor module including a first substrate having an insulating property, a plurality of sensor electrodes over the first substrate, a second substrate having an insulating property over the plurality of sensor electrodes, at least one charge-dispersing film over the second substrate, and a third substrate over the at least one charge-dispersing film. The at least one charge-dispersing film may consist of one charge-dispersing film overlapping all of the plurality of sensor electrodes.
