摘要:
A liquid crystal dispersion display including an opaque first conductive layer including developed silver crystals and having a plurality of first openings for transmission of light; a water permeable coated layer having dispersed liquid crystals in a binder over the opaque first conductive layer; an opaque second conductive layer including developed silver crystals coated over and coextensive with portions of the opaque first conductive layer and formed with second openings which are offset from the first openings; and a structure for changing the electrical potential between the first and second conductive layers so as to effect a change in the dispersed liquid crystals which in a first state causes light which passes through the first openings to be absorbed by the second conductive layer and in a second state which causes light to be scattered and passed out through the second openings in the display.
