BEAM REFLECTING MULTILAYER SHEET, REFRACTOR USING THE SHEET, ILLUMINATING DEVICE, AND LIQUID CRYSTAL DISPLAY DEVICE

摘要

A beam reflecting multilayer sheet is constituted of a beam reflecting resin layer (A) and a resin substrate layer (B) containing 30 mass % or more of an inorganic filler and having a bending modulus of 5 GPa or higher. A beam reflecting multilayer sheet is formed to have a flexible resin layer (C) additionally on the side of the resin-based layer. These multilayer sheets are used to manufacture a reflector, in which at least a reflecting plate, a boss portion for mounting a circuit, a reinforcing rib portion, an optically diffusive plate supporting frame, and, if necessary, a lamp holder, a lamp supporter and an optical diffusive plate supporting pillar are integrally formed. The reflector is used to manufacture an illuminating device. This illuminating device is used to manufacture a liquid crystal display device. It is possible to reduce the number of parts and the assembling steps of the illuminating device. Thus, there are provided the beam reflecting multilayer sheets for forming the lightened and thinned reflector, the reflector using the sheets, the illuminating device having the reflector, and the liquid crystal display device having the illuminating device.
