Light diffuser plate, surface emission light source apparatus and liquid crystal display

摘要

To provide a light diffuser plate which is lightweight and has sufficient strength and is not deformed by heat or humidity, and also has sufficient surface hardness and is also excellent in scratch resistance. A light diffuser plate 3 of the present invention comprises a base layer 8 which is made of a resin composition containing light diffusing particles in an amount of 0.1 parts by mass or more and less than 5 parts by mass based on 100 parts by mass of a propylene polymer, and a surface layer 9 which is integrally laminated on one or both surfaces of the base layer 8 , and the surface layer 9 is made of a resin composition containing particles having a volume average particle diameter of 10 to 200 mum in an amount of 5 to 50 parts by mass based on 100 parts by mass of a propylene polymer.
