LONG LIFE HIGH CONTRAST LIQUID CRYSTAL DISPLAY

摘要

A field effect or twist nematic liquid crystal display is assembled having two transparent substrates with light polarizers affixed to the outwardly facing surfaces of the substrates. The inwardly facing surfaces of the substrate each have deposited thereon predetermined arrays of transparent electrodes. A transparent coating is applied overlying the transparent electrodes on each inwardly facing surface of the two substrates by sputtering or vacuum deposition processes. The inwardly facing surfaces of the coatings are formed to carry uniform unidirectional score marks throughout which are substantially parallel to marks on the same surface. The score marks are placed on the coating surfaces by buffing therefore requiring a moderately soft coating surface. A field effect liquid crystal is placed between the coatings in contact with the surfaces having the score marks thereon. A fluid inpervious seal is placed surrounding the field effect liquid crystal and fused in place for containing the liquid crystal in the assembly and for isolating it from the surrounding environment.
