摘要: A light reflector comprising a biaxially stretched film containing a polyolefinic resin and a filler, wherein said filler is an inorganic filler having an average grain size of 0.1 to 8 &mgr;m and/or an organic filler having a mean dispersion grain size of 0.1 to 8 &mgr;m, and said biaxially stretched film has an area stretched factor of 16 to 80, and having a luminance of 1,200 cd/m2 or above is disclosed. A specific feature of such light reflector of the present invention resides in that improvement in the luminance achieved at low cost is ascribable to the structural feature thereof rather than to the composition.
