  Let $L$ be a finite extension of $\mathbf{Q}_p$. Let $\rho_L$ be a
potentially semi-stable non-crystalline $p$-adic Galois representation such
that the associated $F$-semisimple Weil-Deligne representation is absolutely
indecomposable. In this paper, we study Fontaine-Mazur parabolic simple
$\mathscr{L}$-invariants of $\rho_L$, which was previously only known in the
trianguline case. Based on the previous work on Breuil's parabolic simple
$\mathscr{L}$-invariants, we attach to $\rho_L$ a locally
$\mathbf{Q}_p$-analytic representation $\Pi(\rho_L)$ of $\mathrm{GL}_{n}(L)$,
which carries the information of parabolic simple $\mathscr{L}$-invariants of
$\rho_L$. When $\rho_L$ comes from a patched automorphic representation of
$\mathbf{G}(\mathbb{A}_{F^+})$ (for a define unitary group $\mathbf{G}$ over a
totally real field $F^+$ which is compact at infinite places and
$\mathrm{GL}_n$ at $p$-adic places), we prove under mild hypothesis that
$\Pi(\rho_L)$ is a subrepresentation of the associated Hecke-isotypic subspace
of the Banach spaces of (patched) $p$-adic automophic forms on
$\mathbf{G}(\mathbb{A}_{F^+})$, this is equivalent to say that the Breuil's
parabolic simple $\mathscr{L}$-invariants are equal to Fontaine-Mazur parabolic
simple $\mathscr{L}$-invariants.
