A method of manufacturing an active matrix substrate is provided that uses a technique of transferring a thin film device. In forming thin film transistors and pixel electrodes on an original substrate before transfer, an insulator film such as an interlayer insulation film or the like, is previously removed before the pixel electrodes are formed. Further, the original substrate is separated by exfoliation to transfer the device to a transfer material to cause the pixel electrodes to partially appear in the surface or the vicinity of the surface of the device. This portion permits application of a voltage to a liquid crystal through the pixel electrode.

A liquid crystal composition, comprising a liquid crystal and a polymerizable compound capable of polymerization by means of light, heat, or a combination thereof, is placed in the gap between two parallel substrates on which are formed a pair of electrodes, and the polymerizable compound is polymerized to form a liquid crystal layer and a resin film. A liquid crystal display device is manufactured accordingly. The polymerizable compound comprises a monofunctional polymerizable compound, and the dipole moment of the monofunctional polymerizable compound is 4 debyes or lower. Thus, a liquid crystal display device, with high reliability, and of excellent quality with little or no contrast reduction due to white lines, is provided.

A capture device for remote, virtual on screen data input by hand annotation comprises at least three functional layers including a bottom rigid layer, a middle pressure sensor layer and a top flexible layer. The bottom rigid layer has a surface that provides a mechanical support for writing. The middle pressure sensor layer is adapted to measuring a pressure array or map on the capture active area and to send data representing the measured pressure to a personal computer. The top flexible touch-sensitive passive LCD display layer includes an LCD surface by which whatever is written down on the LCD is impressed graphically due to its liquid crystal physical properties wherein applied pressure changes the crystal particles orientation and light properties, such that when a stylus presses against a writing surface thereof, it leaves a visible trace allowing the user to produce a drawing though no real ink has flown.

A beam steering apparatus includes a first beam steering stage and at least a second beam steering stage arranged in-line with the first beam steering stage. The first beam steering stage includes a first polarization grating comprising a uniaxial birefringent material having a first periodic director pattern, and the second beam steering stage includes a second polarization grating comprising a uniaxial birefringent material having a second periodic director pattern. In nonmechanical embodiments, a polarization selector may be arranged to provide a circularly polarized input beam incident on the first polarization grating. In mechanical embodiments, at least one of the first polarization grating and the second polarization grating may be operable to be independently rotated about an azimuth thereof. Related methods of operation are also discussed.

Oilfield elements are described, one embodiment comprising a combination of a normally insoluble metal with an element selected from a second metal, a semi-metallic material, and non-metallic materials; and one or more solubility-modified high strength and/or high-toughness polymeric materials selected from polyamides, polyethers, and liquid crystal polymers.

A device for displaying images positions a luminescent material between a light source and a liquid crystal display (LCD). The light source, which comprises one or more nonpolar or semipolar III-nitride based light emitting diodes (LEDs), emits a primary light having a specified polarization direction and comprising one or more first wavelengths. This primary light emitted by the light source is a linearly polarized light that eliminates any need for a polarizer. The luminescent material, which comprises one or more phosphors, is optically pumped by the primary light and emits a secondary light having the polarization direction of the primary light, wherein the secondary light is comprised one or more second wavelengths that are different from the first wavelength. This secondary light emitted by the luminescent material is a colored light that eliminates any need for a color filter. The LCD receives the secondary light and displays one or more images in response thereto.

This invention relates to liquid crystal (LC) displays comprising cells of well-defined shape, size and aspect ratio which cells are filled with a liquid crystal composition preferably containing dichroic dye(s), and novel processes for their manufacture.

A wide viewing angle liquid crystal display includes color filters having a quantum dot and scattering particles and liquid crystal layer disposed in a microcavity, a distance between the color filter and the liquid crystal layer being sized to minimize display deterioration due to parallax.
