We prove a lower semicontinuity result for polyconvex functionals of the Calculus of Variations along sequences of maps $u:\Omega\subset\mathbb{R}^n\to\mathbb{R}^m$ in $W^{1,m}$, $2\leq m \leq n$, bounded in $W^{1,m−1}$ and convergent in $L^1$ under mild technical conditions but without any extra coercivity assumption on the integrand.

Keywords: Polyconvexity, Lower Semicontinuity, non-coercive integrand
