Displacement current is that current which comes into play in the region in which the electric field and the electric flux is changing with time.

Displacement current - In electromagnetism, displacement current is a quantity that is defined in terms of the rate of change of electric displacement field. Displacement current has the units of electric current and it has an associated magnetic field.

The physical meaning of this displacement current is that a changing electric field makes a changing magnetic field. To find the direction of the magnetic field produced by this effect we use our usual right-hand rule for currents: point your thumb in the direction of the displacement current (the direction of ), and your fingers will curl around in the direction of the magnetic field.
