摘要： A liquid crystal display has spacers for maintaining a liquid crystal layer and a cell gap between a substrate and an opposite substrate and also has regions either within a single pixel or over two or more pixels. The spacers are of columnar shape elongated from the substrate to the opposite substrate or the other way round, and the columnar spacers are provided in regions in which the liquid crystal layer is thinnest among those regions in which the liquid crystal layer varies in thickness. The structure makes the liquid crystal display having two or more different cell gaps to stably maintain those cell gaps and produces good quality displays.

摘要： A liquid crystal display device includes a ferroelectric liquid crystal layer. The ferroelectric liquid crystal molecules have pretilt directions defined by first direction vectors obtained by orthogonally projecting first imaginary vectors to each surface of a pair of substrates. The first imaginary vectors are parallel to the liquid crystal molecules in the ferroelectric liquid crystal layer in the vicinity of the substrates and directed away from each surface of the pair of substrates toward a center portion of the ferroelectric liquid crystal layer in its thickness direction. The ferroelectric liquid crystal layer has a chevron layered structure. A bending direction of the smectic layers is the same direction as the first direction vector obtained by orthogonally projecting a second imaginary vector to the substrates. The second imaginary vector is parallel to the smectic layers and is included in the same plane with the first imaginary vector and is directed away from the substrates toward the center of the ferroelectric liquid crystal layer. Walls made of insulating non-liquid crystal material are formed between the pair of substrates in a direction perpendicular to the surfaces of the pair of substrates and a light-shielding film is formed on either one of the substrates so that light does not pass through portions of the ferroelectric liquid crystal in a vicinity of a downstream side of the walls along the pretilt direction.

摘要： A liquid crystal display device includes upper and lower substrates having upper and lower electrodes formed on a surface of respective upper and lower substrates, and upper and lower orientation films formed over the surface of respective upper and lower electrodes. A nematic liquid crystal is sandwiched between the upper and lower substrates. A driver mechanism shifts the longitudinal axes of molecules of the liquid crystal, and is adapted to apply a voltage to the liquid crystal for selectively and bistably executing switching between a first state in which the longitudinal axes of liquid crystal molecules adjacent the upper substrate have a tilt angle with respect to the upper substrate and the longitudinal axes of liquid crystal molecules adjacent the lower substrate are parallel to the lower substrate, while the longitudinal axes of liquid crystal molecules adjacent the upper and lower substrates projected on the planes of the upper and lower substrates are oriented in a generally same direction, and a second state wherein the longitudinal axes of the liquid crystal molecules adjacent the lower substrate have a tilt angle with respect to the cross-sectional direction of the lower substrate and the longitudinal axes of the liquid crystal molecules adjacent the upper substrate are parallel to the cross-sectional direction of the upper substrate, while the longitudinal axes of the liquid crystal molecules adjacent the lower and upper substrates projected on the lower and upper substrates are oriented in a generally same direction.

摘要： A large liquid crystal display (100) comprises a light guide plate (3) arranged on the back side of a liquid crystal panel (1). The front surface of the light guide plate (3) is flat, while the back surface thereof is concave. The upper and lower end faces of the light guide plate (3) respectively facing hot cathode fluorescent lamps (2a, 2b) have a convex shape projecting toward the respective lamps. White light from the fluorescent lamps is incident on the upper and lower end faces of the light guide plate directly or by being reflected by reflectors (4a, 4b), and propagates within the light guide plate while being reflected by the front and back surfaces of the light guide plate. At the front surface of the light guide plate, a part of the white light is directed toward the back side of the liquid crystal panel (1) by a light guide portion (5).
