Abstract
There is disclosed a liquid crystal display device comprising two substrates facing and spaced from each other, at least one of the substrates being transparent, electrodes positioned to establish an electric field in the space between the two substrates, one or more photoinitiator or enhancing (PIE) elements located between the substrates, one or more polymer elements located primarily in the vicinities of the PIE elements, the polymer elements located between the two substrates and having been polymerized in situ in response to the PIE material carried on or within the PIE elements, and electrooptic material filling at least a portion of the space between the two substrates.
