Abstract: A ferroelectric liquid crystal device of a cell structure having a suppressed increase of cell thickness along a cell side is constituted by disposing a ferroelectric liquid crystal between a pair of substrates each being provided with an electrode for driving a liquid crystal and disposed opposite to each other. Each of the substrates further has on the electrode at least one layer of an alignment control film subjected to an uniaxial aligning treatment. For suppressing a liquid crystal movement, said alignment film is formed on an uneven surface having a surface unevenness providing a difference in height of at most 50 nm (500 ANGSTROM ) and an average pitch of unevenness of at most 100 nm (1000 ANGSTROM ).

Abstract: A liquid crystal device is constituted by a pair of oppositely disposed substrates having opposing inner surfaces and opposing electrodes thereon, and a chiral smectic liquid crystal disposed between the opposing electrodes. The liquid crystal device has an effective optical modulation region (2) and a peripheral region (3) outside the effective optical modulation region. In the device, liquid crystal molecules in the peripheral region have a pretilt angle ( alpha 2) which is larger than a pretilt angle ( alpha 1) of liquid crystal molecules in the effective optical modulation region. As a result, a local pressure irregularity or a cell thickness change caused by a liquid crystal molecular movement along an extension of the device is effectively suppressed.

Abstract: In a coating method for forming a film of a coating material on a substrate by supplying the coating material from a coating unit to the substrate held by a stage while the coating unit is moved relative to the stage, the stage includes a substrate-holding section and a peripheral section which has a surface higher than that of the substrate-holding section. The coating method includes the steps of mounting the substrate on the substrate-holding section of the stage; forming the film of the coating material so that the coating covers the substrate and extends to the peripheral section; and removing the coating material remaining in the peripheral section by a coating material removing unit after the substrate provided with the film is dismounted from the stage.

Abstract: A ferroelectric liquid crystal device is formed by disposing a ferroelectric liquid crystal between a pair of substrates, each having thereon a group of electrodes for driving the ferroelectric liquid crystal and provided with a uniaxial alignment axis for aligning the ferroelectric liquid crystal molecules. The uniaxial alignment axes provided to the pair of substrates are disposed to intersect each other at a prescribed intersection angle, and the liquid crystal molecules (501) are aligned to provide a director (503) forming a pre-tilt angle ( alpha ) of 5 to 35 degrees with the liquid crystal aligning surfaces (502) of the substrates (101-101a). The ferroelectric liquid crystal device provides an improved contrast as well as a broad drive margin.
