Abstract: This paper considers the travelling wave fronts to a delayed lattice differential equation.The existence of the travelling wave solutions is proved by making use of the technique of the upper and lower solutions developed by J Wu and X Zou in [6].This work extends that of [4] in a general class of nonlinear terms.

Key words: travelling wave front, lattice differential equation, delay, upper and lower solutions
