In displacement reaction one element from its salt is displaced by a more reactive element.
In double displacement reaction exchange of ions take place between two reactants to form new products.

Hey there !
Displacement reaction is a chemical reaction in which a more reactive metal displaced a less reactive metal from its compound.
It is classified into three types :-
1) Thermal decomposition [ heat energy is used ]
2) Electrolysis [ electricity ]
3) Photochemical decomposition. [ sunlight ]
Examples :-
1) Fe + CuSO₄ ---> FeSO₄ + Cu
Iron being more reactive than copper , displaced copper from its compound , copper sulphate .
2) K + AgNO₃ -----> KNO₃ + Ag
Potassium is more reactive than silver ,
hence its displaced silver from its compound , silver nitrate
-------------------------------------------
Double displacement reactions are the chemical reaction in which exchange of ions take place.
It does not happen on the basis of reactivity.
Examples ;-
1) KI + Pb(NO₃)₂ ----> PbI₂ + KNO₃
Here ,
potassium iodide exchanged its ions with lead nitrate.
potassium iodide became potassium nitrate and lead nitrate became lead iodide.
similarly ,
2) BaCl₂ + Na₂SO₄ ------> BaSO₄ + 2NaCl
Hope this Helps you !!
