Abstract
We compute orbi-disk invariants of compact Gorenstein semi-Fano toric orbifolds by extending the method used for toric Calabi-Yau orbifolds. As a consequence the orbi-disc potential is analytic over complex numbers.

Key words: orbifold; toric; open Gromov-Witten invariants; mirror symmetry; SYZ.
