Abstract
There is a liquid crystal display device with two substrates facing and spaced from each other, at least one of the substrates being transparent. Electrodes are positioned to establish an electric field in the space between the two substrates. One or more space elements are located between the substrates. One or more polymer supports are located primarily in the vicinities of the spacer elements. The polymer supports extend between the two substrates and have been polymerized in situ in response to polymerization initiating or enhancing (PIE) material carried on or within the spacer elements. Electrooptic material (e.g., liquid crystal) fills at least a portion of the space between the two substrates.
