Abstract

The present invention relates to a reflective film which is utilized by a reflector of a liquid crystal display device and can provide better reflection performance and less size variation in a heating environment. The reflective film comprises an aliphatic polyester resin and a finely particulate filler and has a lamination structure comprising a layer A having a porosity greater than 5% and a layer B satisfying Formula (I): 0.5 ≤ E'(90)/E'(70) < 1.0, where E'(70) is the storage elastic modulus at 70 degree Celsius and E'(90) is the storage elastic modulus at 90 degree Celsius. Since the layer B has the physical properties satisfying Formula (I), the storage elastic modulus E' should not vary abruptly at least between 70 degree Celsius and 90 degree Celsius so that the size variation under heat resistance test standard (80 degree Celsius) can be reduced.
