A liquid crystal display of the present invention includes a first electrode provided on a substrate, a first liquid crystal layer provided on and in contact with the first electrode, a second electrode provided on and in contact with the first liquid crystal layer, a second liquid crystal layer provided on and in contact with the second electrode, and a third electrode provided on and in contact with the second liquid crystal layer. The display may further include a third liquid crystal layer provided on and in contact with the third electrode, and a fourth electrode provided on and in contact with a third liquid crystal layer. By reducing the thickness of the liquid crystal layers relative to a conventional liquid crystal display, and by providing a plurality of liquid crystal layers, the voltage level required to cause the liquid crystal display to change visual states is substantially reduced without affecting the degree of visual change exhibited by the liquid crystal display. Preferably, at least one of the electrodes is formed of a transparent processable conductive polymer, which is much less expensive than the conventional tin-doped indium oxide materials typically used to form a transparent electrode. The liquid crystal display of the present invention is preferably incorporated in a battery label to display information pertaining to the battery, such as the discharge level of the battery. |
