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.
Claims4
A display element comprising:
- a pair of substrates, at least one of which is transparent;
- a medium, between the substrates, the medium being optically isotropic when no electric field is applied thereon but becomes optically anisotropic when an electric field is applied thereon;
- and
- pixels having at least two domains in which the medium shows optical anisotropies of different directions when an electric field is applied,
- at least one of the substrates having an electrode pair group provided thereon is such a way as to be in each pixel, the electrode pair group including at least two electrode pairs for applying electric fields onto the medium, the electric fields being parallel to the substrates,
- the at least two electrode pairs are parallel to each other and bent in a zigzag shape.
