— In our work, a two‐parameter optimization procedure for a TN display has been performed. The procedure consists of the numerical calculation of the optical parameters of a TN display, such as contrast ratio and luminance as a function of both the LC‐layer dichroic properties and the polarization coefficient of the polarizers used. The calculations have been done for: human eye sensitivity; real spectral characteristics of light sources (both internal and external ones); both the positive and negative modes of operating of the display; real director profile of the LC layer. Additionally, our procedure takes into account the interference phenomena of the display and the quasi‐real properties of the polarizing films. As a result of our work, a close relationship between the TN display optical parameters and the dichroic LC layer and polarizing films used have been obtained. This makes it possible to choose the initial display elements for different display application and user requirements.
