Liquid crystal display with different twisting directions of liquid crystal molecules

A transmissive type liquid crystal display comprising:

• a first substrate having a first electrode and a first alignment film;
• a second substrate having a second electrode and a second alignment film;
• a liquid crystal layer having liquid crystal molecules positioned between the first and second substrates, the liquid crystal layer being doped with a chiral material, wherein the chiral material tends to induce a twisted structure in the liquid crystal layer when an electric field is applied to the liquid crystal layer using the first and second electrodes, wherein the first alignment film has a first alignment direction, the second alignment film has a second alignment direction, the first and second alignment films having orientations that tends to induce another twisted structure in the liquid crystal layer when an electric field is applied to the liquid crystal layer, the direction of twist of the twisted structure induced by the first and second alignment films being different from the direction of twist of the twisted structure induced by the chiral material;
• and a backlight to generate light that is modulated by the liquid crystal layer.
