While there has been considerable modeling of the walls that can form in a LCOS device due to the fringing fields around the pixel electrodes, the procedures often have used simplifications. The importance of understanding these walls when very small pixels are considered has motivated us to look at some of the often‐made assumptions more carefully. In this paper we model the wall due to fringing fields taking into account the topography of the electrodes and pretilt angle, and the optical effect is modeled using the Finite Difference Time Domain (FDTD). The interpixel gap on the non‐ideal light reflection is also studied.
