    摘要： At least one of a pair of substrates constituting a liquid crystal device is provided with a composite alignment film including a homeotropic alignment film region and a homogeneous alignment film region, whereby the liquid crystal in contact with the homogeneous alignment film region is surrounded by the region of liquid crystal in a hybrid or homeotropic alignment state and is stably held in a twit alignment state under no electric field which can be continuously transformed into a bend alignment state. As a result, it is possible to provide a liquid crystal device capable of display by utilizing bend alignment with reduced bending voltage and voltage for holding the bend alignment.

    摘要： A liquid crystal apparatus includes a liquid crystal panel and drive means for driving the liquid crystal panel. The liquid crystal panel includes a pair of oppositely disposed substrates each having an electrode thereon, an alignment film disposed over the electrode on at least one of the substrates, and a liquid crystal disposed between the substrates; the liquid crystal being composed of a plurality of liquid crystal layers each composed of a plurality of liquid crystal molecules. The drive means is suitable for applying to the liquid crystal an electric field insufficient to cause a switching of the liquid crystal but sufficient to cause a reversible change of the liquid crystal layers into a bookshelf structure. As a result, the liquid crystal panel can be provided with a good switching characteristic while effectively suppressing deleterious liquid crystal molecular movement.

    摘要： An optical modulation device is constituted by a first substrate provided with a plurality of first electrodes each comprising a plurality of portions electrically independent of each other, a second substrate disposed opposite to the first substrate and provided with a plurality of second electrodes each confronting a corresponding first electrode, and an optical modulation substance disposed between the first and second substrates so as to form a plurality of pixels each having a particular electrode structure. In the electrode structure, the optical modulation substance is sandwiched between each second electrode and said portions of said corresponding first electrode so as to form a series circuit providing a plurality of capacitance, thus reducing the capacitance for each pixel to improve a switching characteristic while minimizing a defective portion due to a short-circuit between the confronting electrodes.
