Abstract: In a multi-gap semi-transmissive liquid crystal display device, the width of a black matrix (6) is made larger above the region between adjacent ITO transparent electrodes (3) and is made smaller above the region between adjacent Al reflective electrodes (4). This enables a transmissive portion to offer a display with high contrast that does not suffer from afterimage or the like by shielding light from the domain lying between the adjacent pixels, and the reflective portion to offer a brighter display by increasing the aperture ratio thereof by making the black matrix width as small as possible or forming no black matrix.

Abstract: An optical waveguide structure comprises a substrate (12) having first and second groove arrays (8, 10), including grooves (8a-8g, 10a-10h), and an optical waveguide (14), having cladding and core (14b) layered on the substrate between the groove arrays to vertically align the core with cores (2a, 4a) of optical fibers (2, 4) positioned on the grooves. The waveguide has at least one first port (20) aligned with a groove (8d) of the first groove array and at least one second port (22) aligned with a groove (10e) of the second groove array.

Abstract: The strain-managed optical waveguide assemblies of the present invention utilize a large-mode-area (LMA) optical fiber that is annealed in a first bending such that the fiber in that configuration has substantially no axial strain. A fiber support member is then used to support the annealed LMA optical fiber in a second bending configuration that forms within the LMA optical fiber an axial strain profile that reduces stimulated Brillouin scattering (SBS) as compared to the first bending configuration, and that also preferably causes the LMA optical fiber to operate in a single mode. The LMA optical fiber may have a double-clad configuration and include a doped core that serves as a gain medium. The strain-managed optical waveguide assembly can then be used to constitute a fiber amplifier that mitigates the SBS penalty associated with high-power fiber-based optical systems.

Abstract: Disclosed herein is a liquid crystal display that compensates an hourglass phenomenon using a backlight unit. The liquid crystal display includes a liquid crystal panel, a polarizer adhered to the liquid crystal panel, and a backlight unit including a diffuser sheet.

With this construction, the liquid crystal display can avoid the hourglass phenomenon from being observed by a viewer, and prevent non-uniform brightness while improving image quality.

Abstract: The invention is directed to liquid crystal display and electro-optical devices having faster switching times, a wider viewing angle, continuous gray level, improved transmittance of the clear state, approximately no threshold voltage and low power consumption. The aspects of the invention are achieved by a liquid crystal device comprising an orthogonal nematic, smectic or columnar liquid crystal phase, which is uniaxial in absence of electric field, but becomes biaxial when electric field is applied normal to the director (in between electrodes for planar alignment, or in-plane electric field in case of homeotropic alignment). This electric field induced biaxiality (EFIB) mode is provided using any dielectric orthogonal nematic, smectic or columnar bent-core liquid crystal phase. The nature of the switching is dielectric (not piezoelectric) and does not involve variation of layer spacing variation, so as to be mechanically much more stable than prior systems.
