RESIN COMPOSITION, REFLECTOR PLATE AND LIGHT-EMITTING DEVICE

摘要

Disclosed is a resin composition containing a liquid crystal polyester and a titanium oxide filler, wherein when the aluminum content in the titanium oxide filler in terms of aluminum oxide is represented by A (wt%) and the volume average particle diameter of the titanium oxide filler is represented by B (µm), A and B satisfy the following formula (I): A = 0.1 and the following formula (II): A/B2 = 25.  Also disclosed are a reflector plate obtained by molding the resin composition, and a light-emitting device comprising the reflector plate and a light-emitting element.  The resin composition is capable of providing a reflector plate which has a high reflectance and high heat resistance.  By using the reflector plate, there can be obtained a light-emitting device having excellent characteristics such as luminance.
