Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a reflection sheet which can reduce a lamp image easily produced in a thin-type direct backlight. SOLUTION: The reflection sheet contains a thermoplastic resin (A) and at least one of thermoplastic resins (B) which are incompatible with the thermoplastic resin (A). The reflection sheet has an inner layer 11 having a hole stretched in a sheet surface direction and a surface layer 12 including a thermoplastic resin (C) and is constituted of at least two layers: the surface layer 12 and the inner layer 11. The hole 13 has a length mean hole diameter of 6 μm or above in the sheet surface direction in the vicinity 14 of the surface layer of the inner layer 11. COPYRIGHT: (C)2011,JPO&INPIT
