Abstract

A method of manufacturing a light modulating capacitor display by successive operations on an assembly comprising forming a layer of a conductive material on a substrate in a pattern is disclosed. The pattern forms a plurality of fixed electrodes. The pattern forms electrical conductors for driving the fixed electrodes and electrical conductors for driving shutter electrodes. A layer of insulative material is laid over portions of the pattern forming the plurality of fixed electrodes. A shutter electrode forming layer is attached to the assembly. The shutter electrode forming layer has a conductive side and a nonconductive side. The conductive side is placed in facing, contacting relationship to the layer of insulative material and the pattern of conductive material. The conductive material is removed from the shutter electrode forming layer to form groups of shutter electrodes. A plurality of shutters are cut from the shutter electrode forming layer.
