Abstract
A liquid crystal display laminate comprises a liquid crystal layer and a single substrate for confining that layer, allowing the liquid crystal layer to be provided using a wet deposition method such as printing or coating. To improve mechanical stability and provide protection and keep the liquid crystal layer in place, a cover layer may be provided on the liquid crystal layer. The cover layer and liquid crystal layer may together form a stratified-phase-separated composite in which case the liquid crystal layer and the cover layer are provided simultaneously. The display laminate is very thin and light weight. The display laminate may include or be combined with further layers such as orientation layers, electrode layers, polarizers and/or retarders layer to form a fully functional, high contrast display device.
