<P>PROBLEM TO BE SOLVED: To decrease production loss by increasing brightness of a reflective film, improving durability of peripheral members and preventing adhesion of fine foreign matter such as dust. <P>SOLUTION: A white polyester film for a liquid crystal display reflector is provided, which comprises a resin having a glass transition temperature (Tg) of 180°C to 220°C and a MVR (melt volume rate) of 2 to 50 cm<SP>3</SP>/10min (ASTM D1238) (at 260°C under 2.16 kg load), incompatible with polyester. At least one surface of the film shows an average relative reflectance of not less than 97% in a wavelength range from 400 to 700 nm of light. <P>COPYRIGHT: (C)2009,JPO&INPIT |
