Abstract
A liquid crystal display device with a liquid crystal material layer (414) includes a common electrode layer (406) proximate the liquid crystal material layer (414), a patterned metal oxide layer (408) arranged opposite the common electrode layer (406), where the liquid crystal material layer (414) is arranged between the common electrode layer (406) and the patterned metal oxide layer (408). The liquid crystal display device includes a thin, optically clear insulating coating (410) applied to a surface of the patterned metal oxide (408), and a patterned metal oxide mask (412) applied to a surface of the optically clear dielectric coating (410), where the patterned metal oxide mask (412) is electrically coupled to the common electrode layer (406). The liquid crystal display device controls where the electrical field is seen by the liquid crystal material by creating intentional shorts across it where it is not intended to switch.
