发明名称 LIGHT-REFLECTING FILM AND SURFACE LIGHT SOURCE USING SAME
摘要 <P>PROBLEM TO BE SOLVED: To provide a light-reflecting film having superior reflection characteristics and luminance characteristics. <P>SOLUTION: In the light-reflecting film, in which the average reflectance is 80 % or higher and glossiness is different according to the direction of the film surface. When glossiness is G1 in a direction (direction of minimum glossiness) where the glossiness is minimized and glossiness is in a direction orthogonal to the direction is G2, any one of at least equations (1): G2-G1&ge;20 or equation (2): G2/G1&ge;1.2 is satisfied. <P>COPYRIGHT: (C)2004,JPO&NCIPI
