Let us assume an object has started moving from O and initially moved a distance OA along North-East direction as shown in figure.
After the point A , let the object travels along AB as shown in figure in the direction south-east with respect to point A.
 
The net displacement is positive . This consideration is by convention so that displacement at right side of staring point is positive.
--------------------------
 
Now let us consider that , the object moving from B to O as shown in figure in the direction towards west.
 
Now the net displacement is zero . When an object does not move then displacement is zero .
Also when an objects moves and come back to staring point , then displacement is zero.
 ------------------------------------------------
 
Now let us consider the object continues to move along west direction upto the point C as shown in figure.
 
Now the net displacement is negative. This consideration is by convention as explained previously so that
displacement in left side of starting point is negative
