Provided is a laminate which can not only control the amount of external light transmitted, but can also be used as a mirror. A laminatecomprises: a first liquid crystal member; a reflection type polarizing member; and a second liquid crystal member. The first liquid crystal member has first liquid crystal cells with changing orientation states, and a first absorption type polarizing member. The first liquid crystal cells can be switched: between a mode where one type of polarized light of the incident light is blocked and the other type of polarized light is transmitted, and a mode where one type of polarized light of the incident light is blocked and the other type of polarized light is shifted and then transmitted; between a mode where the incident light is transmitted as-is, and a mode where one type of the polarized light is blocked and the other type of polarized light is transmitted; and between a mode where one type of polarized light of the incident light is blocked and the other type of polarized light is transmitted, and a mode where one type of polarized light of the incident light is transmitted and the other type of polarized light is blocked. The reflection type polarizing member receives the light transmitted by the first liquid crystal member, transmits one type of polarized light of the incident light, and reflects the other type of polarized light. The second liquid crystal member has second liquid crystal cells with changing orientation states, and a second absorption type polarizing member. When the reflection type polarizing member has transmitted polarized light, the second liquid crystal cells can be switched between a mode where the polarized light is blocked and a mode where the polarized light is transmitted.

Laminate, light control device, light control member, and vehicle

The present invention is to provide an electromagnetic wave shielding material including a transparent substrate and a convex pattern layer composed of a conductive composition formed in a prescribed pattern on the transparent substrate, wherein the conductive composition contains conductive particles and a binder resin; and in observation of a transverse cross section of the convex pattern layer by electron microscopic photography, at least a part of the conductive particles has a fused continuation and a method for manufacturing the same. The electromagnetic wave shielding material and the method for manufacturing the same include a configuration capable of achieving a lower surface resistivity in an electromagnetic wave shielding material which is required to achieve a much more reduction in a line width of the pattern, specifically, a reduction to a line width of not more than 30 &#x3bc;m, and more preferably not more than 15 to 20 &#x3bc;m and a treatment method capable of reducing the surface resistivity by an easy and short-time treatment.

Electromagnetic wave shielding material, and method for manufacturing same

A metal filmis laminated directly to or by means of an adhesiveto a transparent base sheet. A mesh metal film including lines defining apertures is formed by coating the metal filmwith a mesh resist layerpatterned in a mesh, etching the metal filmthrough the mesh resist layer, and removing the mesh resist layer. The front surfaces and side surfaces of the lines of the mesh metal film are coated with a black coating layer
