Taking the Leray-schauder nonlinear alternative as a tool, the existence of anti-periodic solutions of first neu- tral delay difference equations with parameter is discussed. The existence of anti-periodic solutions is obtained when the pa- rameter belongs to appropriate intervals. Therefore, the sufficient conditions for existence of anti-periodic solutions are ob- tained. The example shows the feasibility of the main results.
