In the present work, the optical chiral properties of a resonant hybrid photonic crystal (RHPC) are studied taking into account the spin-orbit effect of the 2D light-hole exciton. In these systems, the space inversion breakdown of the elementary cell preserves unidirectional exciton–polariton propagation and optical activity occurs, due to the pure dissipative and off-diagonal elements of the material polarization tensor. The non-Bloch solutions of Maxwell equations in such kind of systems are pointed out and their effect on the light propagation and optical rotation is briefly discussed. Finally, the dispersion relation properties of the light-hole exciton polariton are compared with the optical response in a rather large N-cluster of elementary cells 
. The physical parameter values adopted in the calculation are close to 
systems.
