METHOD OF WAFER SCALE FABRICATION AND ASSEMBLY OF A LIQUID CRYSTAL ELECTRO-OPTIC DEVICE

摘要

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.

1. An electro-optic device having at least one liquid crystal cell for providing spatially variable control of light, the liquid crystal cell being provided between a pair of opposed substrates and having a liquid crystal reservoir wall connected between the pair of opposed substrates and containing liquid crystal material in the cell, the reservoir wall being formed by a bottom barrier deposited on a bottom one of the opposed substrates and a top barrier deposited on a top one of the opposed substrates, a boundary between the liquid crystal material and the reservoir wall at each of the pair of opposed substrates being defined by a respective one of the top barrier and the bottom barrier as deposited on their respective substrates.
