Provided are a film which can be decorated even against a three-dimensional shape, is excellent in moldability during decoration (adhesion) on an adherend, is able to reduce concaves and convexes with a variety of sizes which the adherend surface has, and makes an appearance quality favorable; and a decorative molded product having the film. The film is a film including a layer containing a thermoplastic resin, wherein when a highest temperature of glass transition temperatures of the film is designated as Tg [+ C], a temperature T [&#xb0; C.] at which an elongation at break is 50% or more exists in a range of Tg to (Tg+50 [&#xb0; C.]), and when, with respect to concaves and convexes of an abrasive grain surface of a polyester film sheet having, as an abrasive grain, aluminum oxide having a grain size of 12 &#x3bc;m coated thereon, an amplitude relative to a spatial frequency f is designated as A(f); with respect to concaves and convexes of a film surface when adhering the film to the abrasive grain surface at any temperature of the range of Tg to (Tg+50 [&#xb0; C.]) and a pressure of 0.3 MPa, an amplitude relative to the spatial frequency f is designated as A(f); and a ratio of A(f) to A(f) is designated as &#x3d5;(f)=A(f)/A(f), a minimum value fc of spatial frequencies where &#x3d5;(f) is 0.1 is 2.0 mmor less.

This invention provides a methyl methacrylate resin light guide for use in a surface light source device. The methyl methacrylate resin light guide can reduce the occurrence of dark lines and can improve the screen image quality of a surface light source device. The light guide characterized by including a methyl methacrylate resin and fine particles. Herein, not less than 0.01 parts by mass and not more than 0.5 parts by mass of the fine particles are dispersed in 100 parts by mass of the methyl methacrylate resin. In addition, the absolute value of a difference in refractive index between the fine resin particles and the methyl methacrylate resin is not less than 0.001 and not more than 0.02, the fine resin particles have an average particle size of not less than 1 &#x3bc;m and not more than 10 &#x3bc;m.

A backlight device for a liquid crystal display comprising a light diffuser, a light source disposed behind the light diffuser, and a reflector for reflecting light from the light source, in which a liquid crystal panel is disposed in front of the light diffuser and irradiated, from the back side, with the direct light from the light source and the light reflected by the reflector and diffused by and passed through the light diffuser. The light source is of a type which radiates UV-rays and heat along with visible light. The warp and yellowing of the diffuser are suppressed even if the quantity of UV-rays is increased with an increase in the quantity of light from the light source. In a direct-under type backlight device for a liquid crystal display employing the light diffuser, the color difference (&#x394;E) defined in JIS K 7105 after exposed for 500 hours to artificial light employed for artificial light source test defined in JIS h7350-2 is 2.0 or less, and saturated water absorption rate of the light diffuser is 0.9% or less.
