Abstract
In the present paper it is shown that the impact of electric field with optimum amplitude-frequency parameters is sufficient to induce formation of SA liquid crystal (LC) basic optical states. There are stable focal (FC) conic light scattering structures and stable homeotropic (HT) light transmission structures of the SA LC. The threshold of the electrohydrodynamic (EHD) instability and the optical losses of liquid crystal display (LCD) are decreased by the absence of the alignment layers. At the same time LCD design and technology is essentially simplified
