%X In this paper, the upper and lower solutions combining with the monotone itera- tive technique is emploied to study the existence of solutions for first order periodic bound- ary value problems of delay difference equations. Assuming that the upper and lower solu- tions exist, two group of sufficient conditions are obtained to guarantee the existence of extreme solutions of the boundary value problem.
