In physics, more particular in the theory of electromagnetism, the displacement current is the time derivative of the electric displacement D (a vector field closely related to the electric field E). The concept was introduced by James Clerk Maxwell in 1861

It was first discovered by maxwell.
Actually there are two types of currents-
1.conventional current
2.displacement current
Conventional current are those which are present in the conductors while displacement current are found in insulators.
e.g.
The current between the plates of a capacitor are displacement current.
If we denote conventional current as 'ic' and displacement current as 'id' then,
ic+id=c (constant).
Net current is always constant.
Hope it helps.

Y this concept was introduced?
displacement current in the context of capacitors.
It is required to make the conduction current to lead in the circuit. For example when a current flows through an inductor, it lags behind the voltage, but by using a capacitor in a circuit, conduction current in wires can be made to lead the voltage by means of displacement current inside the capacitor and it has vast uses in induction motors, industrial appliances and in our day to day life.
