Light propagation in liquid crystal devices is described by means of rigorous electromagnetic theory. With the numerical finite-difference time-domain method, the field distribution in inhomogeneous molecule arrangements caused by the finite size of the pixel electrodes can be calculated by a full solution of the Maxwell equations. As an example, a two-dimensional calculation of an inversion layer in a twisted nematic display is presented, and the significance of the new method is shown by comparison of the results with those of a one-dimensional Jones calculation.
