RESIN COMPOSITION, REFLECTOR PLATE AND LIGHT-EMITTING DEVICE

摘要

Disclosed is a resin composition containing (A) a liquid crystal polyester and (B) a titanium oxide filler having a volume average particle diameter of 0.27-0.4 µm. The resin composition contains 5-110 parts by mass of the component (B) per 100 parts by mass of the component (A). A reflector plate obtained by using the resin composition and a light-emitting device provided with the reflector plate are also disclosed. By using the resin composition, there can be obtained a reflector plate exhibiting high reflectance to visible light, while maintaining excellent mechanical strength of a liquid crystal polyester. By using the reflector plate, there can be obtained a light-emitting device having excellent characteristics such as luminance.
