ABSTRACT:
A liquid display comprises a first substrate having a plurality of electrodes thereon, a second substrate having a common electrode, and a liquid crystal material disposed between the first substrate and the second substrate. The common electrode has a pattern of openings therein which causes display elements of the display to have more than one liquid crystal domain. The common electrode is otherwise continuous, except where the pattern of openings is located. The liquid crystal display is of the active matrix variety. It may be a multi-domain homeotropic liquid crystal display or a multi-domain twisted nematic liquid crystal display. It may be a crossover type of display wherein gate lines and data lines are disposed on one substrate and insulated from one another at crossover regions, or a non-crossover type with gate lines, pixel electrodes and active devices on one substrate and data lines having a pattern of openings in accordance with the invention on the opposite substrate.
