Characterization of edge effects in twisted nematic liquid crystal displays

We present a model to more accurately describe the optical properties of a twisted nematic liquid crystal display (LCD). In particular, we study the optical properties of molecules near either edge of the LCD that are unable to twist and tilt under the application of an external electric field. The...
