We prove optimal existence results for entropy solutions to some anisotropic boundary value problems like\begin{equation}\label{pro}\left\{\begin{array}{lll}-\sum_{i=1}^N D^i A_i(x, w, \nabla w)= f-\operatorname{div} F(w) \textrm{ in }\Omega, & \textrm{in }&\Omega, \\v=0 & \textrm{on } &\partial \Omega,\end{array}\right.\end{equation}where $ f \in L^{1}(\Omega) $, $ F = (F_{1}, . . . , F_{N}) $ satisfies $ F \in (C^{0}(\mathbb{R}))^{N}. $and $\Omega $ is a bounded, open subset of ${\mathbb{R}^{N}}$, $ N\geq 2$, and the function $A_{i}(x, s, \xi)$ verify the large monotonicity condition. The construction of the proof of our theorem is done by using Minty's Lemma in its modified version.
