摘要
The optical waveguide sheet of the present invention is an optical waveguide sheet for use in an edge-lit backlight unit of a liquid crystal display unit of laptop computers having a housing thickness of no greater than 21 mm, and includes an optical waveguide layer containing a polycarbonate-based resin as a principal component; and a protective layer laminated on the back face of the optical waveguide layer, the protective layer containing an acrylic resin as a principal component, wherein an average thickness of the optical waveguide sheet is no lower than 250 μm and no greater than 600 μm. An average thickness of the protective layer is preferably no less than 10 μm and no greater than 100 μm, and a relative refractive index of the protective layer with respect to the optical waveguide layer is preferably no greater than 0.95.
