摘要： 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.

摘要： A driving circuit for liquid crystal display is disclosed and includes a circuit for outputting driving signals to a ferroelectric liquid crystal display in order to construct visual information in the display and a voltage source for supplying a predetermined voltage such that when the display system is switched off the circuit means outputs an erasing signal to the liquid crystal display for erasing all of the visual information displayed in the display and eliminates phantom figures from appearing when the display is reused.

摘要： 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.
