Title: Liquid crystal lens or beam steering device comprising an alignment layer with a rubbed foundation layer and an ordered surface layer that aligns liquid crystal molecules in a zero field ground state

Abstract: A liquid crystal lens or beam steering device is made by programming alignment surfaces of the LC cell walls using a programming field to align the alignment surface molecules before fixing them. By setting the desired pre-tilt, the lens can operate in the absence of the control field, and power consumption by the control field can be reduced.
