<P>PROBLEM TO BE SOLVED: To provide a luminance uniformizing sheet which does not reduce luminance and can sufficiently uniformize the luminance without thickening the whole, and to provide a planar light source apparatus provided therewith, which has a high luminance and in which emission light is sufficiently uniformized as well. <P>SOLUTION: In the luminance uniformizing sheet, an easily adhesible layer is formed at least on one side of a translucent base material, and the surface of the easily adhesible layer is provided with a white diffusion layer, the surface resistivity measured in accordance with JIS-K6911 of the translucent base material is 10<SP>8</SP>to 10<SP>12</SP>Ω/square, and also, the white diffusion layer is formed so as to be a pattern shape in such a manner that incident light having an ununiform luminance distribution can be uniformized and emitted so as to be the average thickness of 0.5 to 4.0 μm. <P>COPYRIGHT: (C)2010,JPO&INPIT |
