Optical pattern formation in space and time in slab nematic liquid crystal cells is investigated. The nonlinear response of the system is governed by the spatiotemporal diffusion equation for the molecular reorientation while the respective coupled equation for the evolving light pulse may incorporate normal or anomalous temporal dispersion, for the sake of generality in potential applications. Continuous-wave background enhancement of pattern formation is demonstrated. Evolution of the optical field is studied numerically via the beam propagation technique.
