Abstract: A pair of transparent film substrates are provided. A transparent electrode and an orientation film are formed on each of the pair of transparent film substrates in sequence. A liquid crystal is inserted between the pair of film substrates. An orientation process is performed on each of the orientation films such that a visual-angle direction in which a maximum contrast is obtained is a six-o'clock direction or a twelve-o'clock direction based on a direction of the short hand of a clock. Each of the pair of film substrates is an optically anisotropic body, having a retardation value in the range of 5 to 30 nm in the plane of the film substrates. Assuming that long-axis directions denote directions parallel to the longest side of the periphery of the liquid-crystal shutter, the lagging-axis directions in the plane of the film substrates are approximately parallel to the long-axis directions.

Abstract: A method for manufacturing a liquid crystal device in which a pair of substrates are placed in a vacuum chamber, with at least one inlet port provided for communicating with an inner space between the pair of substrates. The vacuum chamber is evacuated and a material including liquid crystals is supplied to the inlet port. The pressure of the chamber is then elevated such that the liquid crystal and other materials are introduced into the space between the pair of substrates by the use of differential pressure between the inside and outside of the space between the substrates. The material including the liquid crystals is maintained at a sufficiently high temperature such that the liquid crystals exhibit isotropic phases.

Abstract: A liquid crystal device can be driven by application of a unipolar electric field to a ferroelectric liquid crystal layer. Without application of an electric field, isotropic characteristics are observed because of a spiral arrangement of the liquid crystal molecules. Under the application of an electric field, a birefringence is observed because of liquid crystal molecules being aligned in one direction. The device can be driven by applying an electric field in one direction and removing the electric field.

Abstract: An improved liquid crystal device is described such as a display. The device comprises a pair of substrates, a liquid crystal layer, an electrode arrangement, and a ferroelectric film. The ferroelectric film is formed on the inside of the substrate by spinning method using a mixture of a ferroelectric material and an organic resin. When coating, the mixture is diluted with a solvent so that the ferroelectric film can be formed as a thin film. In advance of curring, the ferroelectric film is subjected to an electric field and its dipole moment is aligned and fixed in a direction perpendicular to the substrate. In virtue of the dipole moment, the liquid crystal device can be controlled by applying a voltage in one direction with a high stability.

Without application of electric field, isotropic characteristics is observed because of a spiral arrangement of liquid crystal molecules. Under application of electric field, a birefringence is observed because of liquid crystal molecules aligned in one direction. The device can be driven by applying an electric field in one direction and removing the electric field, by using a rectifier in series with each pixel.
