The present invention provides a thermoplastic resin composition for LED reflector plates, which contains 3-100 parts by mass of (B) a white pigment and 5-100 parts by mass of (C) a needle-like or fibrous reinforcing material per 100 parts by mass of (A) a thermoplastic resin, and which satisfies [{the refractive index of the thermoplastic resin (A)} - {the refractive index of the reinforcing material (C)} >= 0.02]. This thermoplastic resin composition for LED reflector plates has excellent reinforcing effect of the reinforcing material and scarcely inhibits light reflection/scattering effect of the white pigment such as titanium oxide. Consequently, the thermoplastic resin composition for LED reflector plates is effective for luminance enhancement and durability improvement of an LED. |
