<P>PROBLEM TO BE SOLVED: To provide an optical sheet having an adhesive layer, capable of mutually sticking a light diffusing member and a luminance control member with high adhesiveness while holding an air layer between the both, and a backlight unit and a display device provided with the same. <P>SOLUTION: The optical sheet 10 includes the light diffusing member 13 which diffusively emits light, the luminance control member 17 which controls the emitting-directional luminance of the light, the adhesive layer 18 which bonds the light diffusing member 13 to the luminance control member 17, and the air layer 28 provided between the light diffusing member 13 and the luminance control member 17, in which light passed through the air layer 28 is used as a liquid crystal display illuminating light. The adhesive layer 18 includes flow preventing fine particles 30 dispersed in an adhesive composition 32, the gel fraction of the adhesive layer 18 is 70-80%, and the thickness of the adhesive layer 18 ranges from 5-60 μm. <P>COPYRIGHT: (C)2009,JPO&INPIT |
