A new technique is offered to establish the criteria of boundedness for infinite delay differential equations.The main idea is that several Liapunov functions (or functionals) are adopted,each of which involves partial components of x (or φ) so that the conditions ensuring the required boundedness are less restrictive.Some examples are given to illustrate the advantages of the obtained results.
