In this study, we performed a three‐dimensional computer simulation for the electro‐optical characteristics of a super in‐plane switching liquid crystal displays(Super IPS‐LCDs) in a unit pixel of TFT‐LCDs, for the first time, and compared the results with experiments. The dynamic equation of continuum theory for liquid crystals is based on a tensorial formulation. As a numerical technique, we used a finite difference method(FDM) suitable for highly nonlinear equations. As a result, we confirmed that the simulation results such as a transmission profile over a pixel and an average transmittance as a function of applied voltage showed good agreement with the experimental results. We also revealed that Super IPS‐LCDs show good wide viewing angle characteristics with contrast ratio of more than 50:1 up to a polar angle of ±90° both in the horizontal and the vertical directions.
