It is generally considered that the symmetric chevron is the lowest energy layer structure. However, we show that for SSFLC devices with a twisted director configuration that an asymmetric layer structure may be preferred. For typical cell parameters, we find that the lowest elastic energy condition is for the apex located at about 1/3 of the cell thickness. In this paper, the effect of cell and material parameters, as well as experimental data will be presented.
