Abstract
Provided is an electro-optic device having reduced power consumption. More specifically, an electro-optic device is provided comprising: a liquid crystal layer between a pair of opposing transparent substrates; a patterned electrode set positioned between the liquid crystal layer and the inward-facing surface of the first transparent substrate; a conductive layer between the liquid crystal layer and the inward-facing surface of the second transparent substrate; and means for applying voltage to the patterned electrode set and the conductive layer, wherein the voltage applied to the conductive layer is below the threshold voltage (the RMS voltage difference above which the optical transmission of the liquid crystal layer changes).
