Inducing tilted parallel alignment in liquid crystals

摘要

An untreated substrate (42) is treated prior to use to induce a near-parallel orientation of a liquid crystal director relative to the untreated substrate (42). A layer (44) of silica is deposited on the untreated substrate (42) by in-line magnetron sputtering as the untreated substrate (42) is moved past the sputtering target, and the silica-coated substrate (42) is thereafter treated with an alcohol. The alcohol-treated substrate (20) is covered with a layer of the liquid crystal.
