ABSTRACT:
A display element has an arrangement that allows the pixel to have at least two domains in which the medium shows optical anisotropies of different directions when a force (for example, an electric field) is applied or when no force is applied. It is preferable that directions of the optical anisotropies occurred in the respective domains when the electric field is applied respectively have 45 degrees±10 degrees with absorption axes of polarizers, and that the directions of the optical anisotropies occurred in the respective domains when the electric field is applied make 90 degrees±20 degrees.
