This paper is concerned with the linear delay partial difference equation A m , n = ∑ i = 1 u p i A m − k i , n − l i + ∑ j = 1 v q j A m + τ j , n + σ j , where p i and q j are r × r matrices, A m , n = ( a m , n 1 , a m , n 2 ,   … , a m , n r ) T ,   k i ,   l i   ,   τ j and σ j are nonnegative integers, u and v are positive integers. Sufficient and necessary conditions for all solutions of this equation to be oscillatory componentwise are obtained.
