The geometrical optics approach (GOA) is applied to the propagation of light through liquid crystal films whose director varies in three spatial dimensions. As an example of application, the GOA is applied to the calculation of light transmittance for the case of a LCD cell which exhibits the homeotropic to multidomainlike (HMD) transition. Comparison with Jones calculus is also provided. For smaller geometries, where the Jones calculus breaks down, the GOA provides a fast, accurate method for calculating the optical performance of LCDs.
