Aim. The aim of this article is to search for the design of an LC light modulator based on a nematic with minimal response time. Methodology. The research method is computer simulation of the integral characteristics of various designs of the LC modulator. The research procedure included a comparison of the integral characteristics of various modulator designs. Results. As a result of the studies, a linear regression was found depending on the total response time of the LC modulator on the twist angle of the nematic structure. It has also been shown that an LC modulator made on the basis of an LC structure with a swivel angle of 270° under antisymmetric boundary conditions with small pre-tilt angles on orienting substrates, operating in the waveguide mode and using a phase film compensator, has optimal integral characteristics. Research implications is to detect linear regression as a function of the total response time of the LC modulator on the twist angle of the nematic structure. The practical significance of the work lies in the fact that the optimal design of the LCD modulator was found, which simultaneously has a small total response time (less than 4 milliseconds) and an acceptable level of contrast ratio (at least 300: 1).
