A computer simulation of characteristics of the LC shutter based on π-cells for 3D applications for various values of the pre-tilt angles of LC molecules placed onto orienting surfaces was performed. The boundary conditions for π-cells with twist angles of the LC structure equal to 180° or 0° were found, which allow to increase the optical and dynamic characteristics of the standart LC shutters on π-cells. It is shown that the violation of the antisymmetry of the boundary conditions in π-cells leads to a significant deterioration of the LC shutter characteristics.
