A reflector having a structure in which a high refractive index layer, a low refractive index layer, and a metal layer mainly composed of silver or aluminum are sequentially arranged on a polymer base. The reflector can realize a higher reflectance than the conventional reflective bodies by using a polymer base wherein the atoms measured by XPS which constitute the surface of the polymer base are substantially identical with those constituting the inside of the polymer base. Furthermore, such a reflector can be used for a reflector, a reflector under a light-guiding plate, a backlight device and a liquid crystal display. The polymer base can be obtained by bringing a polymer base and a liquid into contact with each other.

Reflector, use thereof, and method for producing reflector

An object of the invention is to provide a reflector using a metal thin film layer, particularly a reflector having higher reflectance than in the prior art. Specifically, studies have been made to provide a reflector which exhibits a superior reflection-increasing effect. As a result, it has been found that if the thickness of a low refractive index thin film layer (B) which comes in contact with a metal thin film layer (A) is controlled so that it is within a range of 0.7 &#x3bb;/8n&#x2013;1.3 &#x3bb;/8n, a reflector having an arrangement of metal layer (A)/low refractive index thin film layer (B)/high refractive index thin film layer (C) exhibits reflectance which is extremely superior than in the prior art over a wide wavelength range. More specifically, it exhibits higher reflectance than a pure silver single film does, and a reflector superior in durability can be obtained. The lamp reflector, reflector under the light-guiding plate of the invention uses the above-mentioned reflector; therefore, if it is applied to each display device, high brilliance and vivid image can be realized. Further, since the liquid crystal display device of the invention uses the above-mentioned reflector, a clear vivid image can be realized.

Reflector and application thereof

A laminate is provided that can easily attain safety standards, such as impact resistance, while cost reduction is aimed for, for example, when the laminate is provided on a display viewing surface. A display apparatus using the laminate is also provided. By using a filter for a display having a specified parameter, for example, containing a transparent adhesive layer or a transparent resin layer having a specified Young's modulus and a specified thickness, impact resistance is enhanced. By using the filter for a display containing an impact absorption layer having a specified penetration and a specified thickness, impact resistance is enhanced.

Laminate and display apparatus using the same

The display filter is constituted by laminating a transparent adhesive layer (C)containing dye, a polymer film (B), a transparent electrically conductive layer (D), a transparent adhesive layer (E), and a functional transparent layer (A)having an anti-reflection property, a hard coat property, a gas barrier property, an antistatic property and an anti-fouling property sequentially in this order, adhered on a display area; on this occasion, the transparent electrically conductive layer (D)is grounded to a ground terminal of the display via an electrodeand an electrically conductive copper foil adhesive tape
