Let = ( , ∧, ∨) be a lattice with a least element called zero and denoted by 0. The annihilating-ideal graph of , denoted by ( ), is a graph whose vertex-set is the set of all non-trivial ideals of and, for every two distinct vertices and , is adjacent to if and only if ∧ = {0}. In this paper, we study some properties of ( ). Also, we completely determine when the annihilating-ideal graph is complete bipartite, split and end-regular.
