LIQUID-CRYSTAL INDICATOR AND METHOD OF ITS MANUFACTURE Russian patent published in 1997 - IPC

FIELD: data-display devices. SUBSTANCE: liquid-crystal indicator uses two transparent glass plates with a transparent current-conducting layer in the form of a preset indication pattern and an orienting layer connected in a pack applied onto them in succession. In addition, use is made of an insulating and current- conducting layers that are placed on each plate between the current-conducting and orienting layers; the topological patterns of the current-conducting layers have different configurations. Transparent current-conducting layers are applied onto the electrode plates; and electrodes are formed. Operations of application of transparent conducting layers onto the electrode plates and formation of image electrodes are performed at least in two levels, between which an insulating layer is applied; formation of image electrode is accomplished by the method of photolithography, both in the first and second levels use is made of masks with different patterns. EFFECT: improved design. 2 cl, 2 dwg
