Abstract
A stacked liquid cell, such as a stacked liquid crystal cell, comprises a stack of liquid layers and substrate layers between which the liquid layers are dispersed. The stack comprises a liquid and polymeric substrate layers made from a stratified-phase-separated composite. Being part of a stratified-phase-separated composite, in particular one manufactured in accordance with a single-substrate method, the polymeric layer may have a relative small thickness compared a conventional substrate layer which results in a stacked liquid cell having a reduced thickness or, more particular, a stacked liquid cell having a reduced thickness between subjacent liquid layers giving a reduction in parallax effects.A method of manufacturing a liquid cell involves stratifying, on a substrate, a layer of stratified-phase-separable composition into a liquid layer and a polymeric layer to form a stratified-phase-separated composite, the polymeric layer serving as one of the substrate of the liquid cell.
