Patent ID: 7298438

Claim:
A semitransparent reflector comprising: a multi-layered, biaxially-oriented film comprising a base layer (A) and protective layers (B) and (C) provided on the base layer (A), wherein the base layer (A) has flaky pores (D) and comprises a thermoplastic resin, a flaky inorganic fine powder and/or an organic filler, and the multi-layered, biaxially-oriented film satisfies the following optical characteristics (1) and (2): 10%≦T≦80%, (1) 20%≦R≦90%, 80%≦( T+R )≦100% 8%≦( R−R d )≦30%, (2) where T indicates the whole light transmittance (%) of the reflector, R indicates the whole light reflectance (%) thereof, R d indicates the whole light diffusion reflectance (%) thereof.
