In this paper, we study the problem

- diva(x,u,∇u )- div ϕ(u)+ g(x,u) = f

in the framework of Orlicz spaces. The main contribution of our work is to prove the existence of a renormalized solution without any restriction on the N  -function of the Orlicz space.

Key words: Orlicz Sobolev spaces, boundary value problems, truncations, renormalized solutions.
