This paper is concerned with the existence of extreme solutions of the periodic boundary value problem for a class of first order impulsive functional differential equations. We introduce new concept of lower and upper solutions and present that the method of lower and upper solutions coupled with monotone iterative technique is still valid. Meanwhile, we extend previous results.
