摘要： There are disclosed an optical storage device for accessing an optical recording medium such as a phase change type of optical disk and an optical magnetic disk, and a liquid crystal device preferably applicable to such a optical storage device. The liquid crystal device has a structure that two liquid crystal layers, each of which has stripe-like shaped electrodes arranged in a direction perpendicularly intersecting one another, are superposed. This structure makes it possible to effectively correct an aberration caused by a change in a depth from a surface of an optical recording medium to a condensing point, for example, in cases of unevenness in thickness of a protective layer and a multi-layer recording.

摘要： The present invention relates to a driving method of a liquid crystal display device using an OCB (optically compensated birefringence) which realizes a wide view-field angle and high-speed response, and has an object of providing a driving method of a liquid crystal display device which method causes an OCB cell to transfer from a splay orientation state to a bend orientation state in short time.In a driving method of a liquid crystal display device using an OCB cell, gate on/off periods of a TFT are controlled at a start of a display operation, each pixel is caused to have bend orientation by a strong electric field that is generated between a gate electrode and a common electrode, and, at the same time, a voltage that is higher than that to generate an electric field necessary to maintain bend orientation is applied between a display electrode and the common electrode, to thereby effect transfer to bend orientation in short time.

摘要： A liquid crystal display device of high display quality and superior sharpness is presented. Large bumps and small bumps made of synthetic resin material are formed on a glass substrate. The bottom diameters of the large bumps and small bumps are defined, for example, at 5 .mu.m and 3 .mu.m, respectively, and their interval is at least, for example, 2 .mu.m or more. Covering these bumps and filling the recesses among the bumps, a smoothing film is formed. On the smoothing film, a reflective metal film made of metal material such as aluminum is formed. This reflective a metal film is formed in plural rows in a longitudinal band form. On the glass substrate, the bumps, smoothing film, and reflective metal film are combined to compose a reflector. An orientation film is formed on the reflective metal film. By the electric field applied in the liquid crystal layer so as to be in the light shielding state when the retardation .DELTA.n.sub.1 d.sub.1 of the liquid crystal cell and the retardation .DELTA.n.sub.2 d.sub.2 of the substrate possessing optical phase compensating function satisfy .vertline..DELTA.n.sub.1 d.sub.1 -.DELTA.n.sub.2 d.sub.2 .vertline./.lambda.=0.25+m/2.+-.0.1 (m=0, 1, 2, . . . ), and in the light transmitting state when satisfying .vertline..DELTA.n.sub.1 d.sub.1 -.DELTA.n.sub.2 d.sub.2 .vertline..lambda.=m/2.+-.0.1 (m=0, 1, 2, . . . ), by crossing the director direction of the liquid crystal molecules of the liquid crystal cell and the slow direction of the substrate possessing optical phase compensating function almost orthogonally, the value of .vertline..DELTA.n.sub.1 d.sub.1 -.DELTA.n.sub.2 d.sub.2 .vertline./.lambda. is varied, and these two states are used to present a display. Further, the absorption axis or transmission axis of the polarizer is set at 30.degree. to 60.degree. to the director direction of the liquid crystal molecule of the liquid crystal cell to produce a reflective type liquid crystal display device with no parallax, high contrast, high sharpness, and high display quality.

摘要： A homeotropic liquid crystal display device compensated for the anisotropy of the homeotropically oriented nematic liquid crystal layer, by anisotropy compensating means comprising at least two anisotropic (e.g. uniaxial) films having their optic axes disposed to form a right angle in a plane parallel to the substrate to form an optically negative activity in the direction perpendicular to the substrate. This optically negative activity is so selected to compensate the positive optical anisotropy of the nematic liquid crystal when oriented homeotropically in the absence of electric field.

摘要： An illuminating device capable of improving display luminance while decreasing light leakage in a range with a large view angle and a display unit are provided. In a light modulation device bonded to a light guide plate, a light modulation layer containing a bulk and microparticles is provided. Both the bulk and the microparticles have optical anisotropy, and each response speed to an electric field is different from each other. Thereby, by controlling the electric field, each optical axis orientation of the bulk and the microparticles is able to correspond with each other, or is able to be different from each other.
