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: An image erasing device for erasing an image formed erasably on a recording medium is provided. An image display apparatus equipped with the image erasing device, and an image recording apparatus equipped with the image erasing device are also provided. The image erasing device comprises a means (3,3',3'') for feeding the recording medium stepwise, and a cleaner (7) for erasing the image formed on the recording medium by independently scanning the recording medium perpendicularly to the direction of feeding of the recording medium while the recording medium stays stationary.

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 ).
