Abstract: An electro-optic device having at least one liquid crystal cell for providing spatially variable control of light includes: a pair of opposed substrates sandwiching a liquid crystal layer therebetween; a pair of electrodes for applying an electric field therebetween, each electrode being deposited on a corresponding substrate; and a liquid crystal reservoir wall defining a lateral extent of the liquid crystal layer between the substrates. The reservoir wall includes: a first bottom barrier deposited on a bottom one of the pair of substrates; and a second curable top barrier deposited on the top substrate outside the first barrier. The first barrier and second uncured barrier are configured to merge on contact to retain liquid crystal material inside the reservoir wall prior to curing the second barrier. Also, a method of wafer level manufacturing and assembly of a liquid crystal optical device.
