The main aim of this work is a presentation of the significance of the numerical optimization procedure for the TN liquid crystal display design process. The assumptions for calculations of such optical parameters as contrast ratio and luminance are presented. The way of measurements of optical parameters (refractive indices and absorption coefficients) for such the display elements as glass, conductive layer, polarizers, etc., which makes it possible to apply these results directly in the computer program worked out by the author, is described. The calculated results of the contrast ratio and luminance for TN transmissive and reflective display are presented. The optimization procedures for negative mode, and for transmissive and reflective type of the display were performed in an independent way.
