Abstract: According to one embodiment, a sensor-equipped display device includes a drive electrode, a detection electrode including a first electrode and a second electrode disposed such that a gap is formed between the first electrode and the drive electrode and a gap is formed between the second electrode and the drive electrode, both of which change corresponding to a pressing force applied to the first and second electrodes, a driver configured to write a write signal to the drive electrode to produce a sensor signal, and a detector. The detector detects a position and a pressing force of an object on the basis of a change in a first capacitance between the first electrode and the drive electrode and a change in a second capacitance between the second electrode and the drive electrode.
