Abstract
A liquid crystal device including a liquid crystal layer having liquid crystal which demonstrates an optically isotropic property when no electric field is applied and demonstrates an optically anisotropic property which is proportional to the square of the electric field strength when electric field is applied, and a pair of substrates which sandwich the liquid crystal layer, including sub-pixel areas each including a reflective display area for reflective display and a transmissive display area for transmissive display; and first and second electrodes provided in both of the reflective display area and the transmissive display area, wherein the liquid crystal layer is driven by an electric field generated between the first electrode and the second electrode, and wherein the distance between the first electrode and the second electrode in the transmissive display area is smaller than the distance between the first electrode and the second electrode in the reflective display area.
