Abstract
A liquid crystal device including a first electrode substrate, a second electrode substrate and a liquid crystal layer is provided. The liquid crystal layer is disposed between the first electrode substrate and the second electrode substrate. The liquid crystal layer comprises liquid crystal molecules and particles. The liquid crystal molecules are vertically aligned when the applied voltage between the first electrode substrate and the second electrode substrate is less than a threshold voltage. The arrangement of the liquid crystal molecules is changed so as to produce optical changes in the liquid crystal device when the applied voltage between the first electrode substrate and the second electrode substrate is not less than the threshold voltage.
