A polarizing system having a light source (23) and a polarizing device (10). The polarizing device having a substrate (18) and a plurality of generally parallel thin, elongated elements (12) disposed on or in the substrate. The polarizing device is disposed in an unpolarized source light beam (22) for transmitting a transmitted light beam (24) having a first polarization and reflecting a reflected light beam (26) having a second polarization.

Polarizer apparatus for producing a generally polarized beam of light

An image projection system having a wire grid polarizing beam splitter (4) which functions as both the polarizer and the analyzer in the system. A light source (20) produces a light beam directed at the beam splitter (14) which reflects one polarization and transmits the other. A liquid crystal array (26) is disposed in either the reflected or transmitted beam. The array modulates the polarization of the beam, encoding image information thereon, and directs the modulated beam back to the beam splitter. The beam splitter again reflects one polarization and transmits the other so that the encoded image is either reflected or transmitted to a screen (25). The wire grid polarizing beam splitter is capable of being oriented at various angles with respect to the source light beam and modulated beam, and accepts relatively divergent light.

The object of this invention is to enhance the display quality of reflection type liquid crystal display device having the constitutions of an organic insulating film is formed on a thin film transistor formed on a substrate, and contact holes and bumps are formed at the positions for forming reflection electrodes on the organic insulating film. The reflection electrodes are formed thereon, and drain electrodes and reflection electrodes 38 are connected through the contact holes. The effect of this invention is since the bumps are formed only in the portions of the reflection electrodes, patterning of the reflection electrodes is easy, and insulation failure between source bus wirings and reflection electrodes does not occur, and the display quality is enhanced.

A polarizing device, such as a wire-grid polarizer, includes a substantial mono-layer of a corrosion inhibitor without adversely affecting the optical properties of the polarizing device. The polarizing device can include an optical element and a nano-structure, such as an array of a plurality of spaced-apart, elongated elements disposed on a substrate. The corrosion inhibitor is chemically bonded to surfaces of the elements to form the mono-layer. The mono-layer can have a thickness less than 100 Angstroms. A method of forming the substantial mono-layer can include treating the polarizing device with an amino phosphonate, such as a nitrilotris (methylene) triphosphonic acid.

Corrosion resistant wire-grid polarizer and method of fabrication

A reflective liquid crystal display device comprising a reflector with a number of small convex portions of the same shape is provided. The reflector is formed by patterning a photosensitive resin applied to one surface of a core substrate to a predetermined pattern so as to form a number of small convex portions, heat-treating the surface having the convex portions, and covering the surface with a reflective film. By suitably selecting the shape of the convex portions, the reflective properties of the reflector are controlled.
