REFLECTOR AND APPLICATION THEREOF |
摘要 |
<p>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 0.7lambda/8nL-1.3lambda/8nL, 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, light-guiding plate lower reflector 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.</p> |
