Abstract

We present wide-viewing characteristics of a twisted nematic liquid crystal display (TN LCD) achieved by adopting dielectric surface gratings (DSGs) as alignment layers. The experimental data and the numerical analyses consistently show that the optical compensation effect inherent to the TN LCD with the DSGs greatly reduces the contrast inversion of the TN LCD.
