Display device with touch detection function

A display device with a touch detection function, the display device comprising:

• a first substrate having an input surface;
• a touch detection electrode provided to the first substrate and facing the input surface;
• a first electrode provided to a second substrate and facing the touch detection electrode;
• a second electrode facing the first electrode with a dielectric layer interposed between the first electrode and the second electrode;
• a touch detection controller configured to detect contact with or proximity to the input surface by a detection target object based on capacitance between the first electrode and the touch detection electrode;
• and
• a force detection controller configured to detect a force applied to the input surface by the detection target object based on capacitance between the first electrode and the second electrode and calculate a force detection value indicating the force,
• wherein the force detection controller is configured to correct the force detection value based on a first capacitance value and a second capacitance value,
• wherein the first capacitance value is a capacitance value between the first electrode and the touch detection electrode while the detection target object is neither in contact with nor in proximity to the input surface, and
• wherein the second capacitance value is a capacitance value between the first electrode and the touch detection electrode at a non-contact position at which the detection target object is neither in contact with nor in proximity to the input surface while the detection target object applies the force to the input surface.
