Liquid crystal q-Airy-plates with director distributions integrated by q-plates and polarization Airy masks are proposed demonstrated via the photoalignment technique. Single/dual vortex beams of opposite topological charges orthogonal circular polarizations directly generated polarization-controllable characteristic. The singular phase part is verified both astigmatic transformation digital holography. trajectory investigated, manifesting separate propagation dynamics optical vortices beams. Meanwhile, still keep their intrinsic transverse acceleration, self-healing, nondiffraction features. This work provides a versatile candidate for generating high-quality
