An electrochromic light adjusting member sequentially includes a transparent substrate, a light transmitting electrically conductive layer, and an electrochromic light adjusting layer. The light transmitting electrically conductive layer sequentially includes a first indium-based electrically conductive oxide layer, a metal layer, and a second indium-based electrically conductive oxide layer.

Electrochromic light adjusting member, light transmitting electrically conductive film, and electrochromic light adjusting element

A depolarizing film of the present invention comprises a film containing at least one liquid crystal compound, wherein the liquid crystal compound comprises a liquid crystal compound (1) that satisfies the relation: 0.05&#x2266;&#x394;n&#x2266;0.5, with the proviso that &#x394;n=ne&#x2212;no, ne represents an extraordinary-ray refractive index, and no represents an ordinary-ray refractive index, and the film has a haze value of 15% or less and a thickness of 1 &#x3bc;m to 10 &#x3bc;m.

Depolarizing film, method for production thereof, optical film, and liquid crystal display

Disclosed herein is a depolarizing film which is excellent in productivity and can have a large area. The depolarizing film is obtained by using birefringent very short fibers instead of inorganic birefringent crystals, such as calcite, for use in conventional depolarizing elements.

Depolarizing film, process for producing the same, and liquid-crystal display

A method for manufacturing liquid crystal alignment film of the present invention comprises the steps of: (1) aligning a transparent substrate film by rubbing; (2) laminating a surface protective sheet having a release force of 0.5 N/50 mm or less onto an aligned face of the transparent substrate; (3) coating a liquid crystal material comprising a liquid crystal monomer and/or a liquid crystal polymer onto the aligned face after releasing the surface protective sheet; and (4) fixing the liquid crystal material after aligning the liquid crystal material. The method can make satisfactorily align the liquid crystal material on the substrate.

Method for manufacturing liquid crystal alignment film, liquid crystal alignment film, optical film and image viewing display

A polarizing plate with optical compensation layers that performs a wide viewing angle compensation with respect to a liquid crystal cell, allows circularly polarized light to be obtained over a wide range of light wavelengths, contributes to the reduction in thickness, prevents thermal irregularity from occurring, and can effectively prevent light leakage from occurring in a black display. The polarizing plate includes a polarizer, a first optical compensation layer, and a second optical compensation layer that are stacked together in this order. The first optical compensation layer is formed of a liquid crystal compound and has a relationship of nx&#x3e;ny=nz and an in-plane retardation Reof 100 to 170 nm. The second optical compensation layer has a relationship of nx=ny&#x3e;nz and a thickness direction retardation Rthof 30 to 400 nm. The angle formed between the absorption axis of the polarizer and the slow axis of the first optical compensation layer is in the range of 'plus' or 'minus' 25 to 65 degrees.

Polarizing plate with optical compensation layer, method of producing the same, and liquid crystal panel, liquid crystal display, and image display including the same

The present invention provides a method of producing an elliptically polarizing plate including the steps of: forming a first birefringent layer on a surface of a transparent protective film; laminating a polarizer on a surface of the transparent protective film; forming a second birefringent layer on a surface of the first birefringent layer; and forming a third birefringent layer on a surface of the second birefringent layer. The first birefringent layer is arranged on the opposite side against the polarizer with respect to the transparent protective film. The step of forming the first birefringent layer includes the steps of: applying a liquid crystal material onto a substrate subjected to an alignment treatment; treating the applied liquid crystal material, so as to form the first birefringent layer on the substrate; and transferring the first birefringent layer onto a surface of the transparent protective film.
