<P>PROBLEM TO BE SOLVED: To provide a light reflection plate capable of sufficiently preventing yellowing due to UV exposure at low cost. <P>SOLUTION: The light reflection plate is composed of a thermoplastic resin sheet having fine air bubbles or pores. The air bubbles or pores are exposed on at least one of the surfaces of the thermoplastic resin sheet. The light reflection plate is obtained, for example, by a method of cutting the thermoplastic polyester foam sheet 20 having fine air bubbles 18 so that a cut surface 22 perpendicular to the thickness direction may be formed. <P>COPYRIGHT: (C)2010,JPO&INPIT |
