<p><P>PROBLEM TO BE SOLVED: To provide a reflection sheet which can reduce a lamp image easily produced in a light-saving direct backlight. <P>SOLUTION: The reflection sheet includes: an inner layer which includes a thermoplastic resin (A) and at least one sort of resin (B) incompatible with the thermoplastic resin (A) at temperature where the thermoplastic resin (A) can be stretched; and a surface layer which includes a thermoplastic resin (C) and a dispersing agent with an average particle size of 0.1 to 20μm, wherein the reflection sheet is constituted of at least two layers consisting of the inner layer and the surface layer. Refractive index difference between the thermoplastic resin (C) and the dispersing agent is in a range of 0.02 to 1.50 and satisfies relational formula (1): 0.015≤▵n×w≤0.35, wherein▵n denotes refractive index difference (absolute value) between the dispersing agent and the thermoplastic resin (C) and w denotes content of the dispersing agent in the surface layer (g/m<SP>2</SP>). <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
