This article deals with the global stability of traveling waves of a spatially discrete diffusion system with time delay and without quasi-monotonicity. Using the Fourier transform and the weighted energy method with a suitably selected weighted function, we prove that the monotone or non-monotone traveling waves are exponentially stable in $L^\infty(\mathbb{R})\times L^\infty(\mathbb{R})$ with the exponential convergence rate $e^{-\mu t}$ for some constant $\mu>0$.
