Abstract

A liquid crystal display includes a first substrate having a first electrode and a first alignment film, a second substrate having a second electrode and a second alignment film, and a liquid crystal layer having liquid crystal molecules between the first and second substrates. The liquid crystal layer is doped with a chiral material that tends to induce a twist in directors of the liquid crystal molecules when an electric field is applied to the liquid crystal layer using the first and second electrodes. The first alignment film has a first alignment direction, the second alignment film has a second alignment direction, and the first and second alignment films have orientations that tend to induce a twist in the directors when an electric field is applied to the liquid crystal layer, in which the direction of twist induced by the first and second alignment films is different from the direction of twist induced by the chiral material. The display includes a reflective layer to reflect
