    • A backlight (illumination device; 2) of the present invention includes: multiple light sources (5); multiple light guide plates (7, 17, . . . ) for causing surface emission of light from the light sources (5); and a diffusing plate (8) for diffusing light from the light guide plates (7, 17, . . . ), the diffusing plate (8) being provided so as to be separate from and face the light guide plates (7, 17, . . . ). Each of the light guide plates (7, 17, . . . ) includes: a light-emitting section (7b) having a light-emitting surface (7a); and a light guide section (7c) for guiding, to the light-emitting section (7b), light from the light sources (5), a light-emitting section (17b) of the first light guide plate (17) being provided above a light guide section (7c) of the second light guide plate (7) adjacent to the first light guide plate (17). A light amount adjusting section (11) for reducing the amount of light incident on it is provided so as to be separate from the diffusing plate (8) and so that the orthogonal projection of the light amount adjusting section (11) onto the light-emitting region covers the boundary between any adjacent light guide plates (7, 17, . . . ). This allows for production of a tandem-type illumination device having further improved luminance uniformity.
    • 本发明的背光(照明装置; 2)包括:多个光源(5); 用于引起来自光源(5)的光的表面发射的多个导光板(7,17 ...)。 以及用于漫射来自导光板(7,17)的光的漫射板(8),扩散板(8)设置成与导光板(7,17)分开并面对, ...) 每个导光板(7,17)包括:具有发光表面(7a)的发光部分(7b); 以及用于将来自所述光源(5)的光引导到所述发光部(7b)的导光部(7c),所述第一导光板(17)的发光部(17b)设置在上述 与第一导光板(17)相邻的第二导光板(7)的导光部(7c)。 设置用于减少入射到其上的光量的光量调节部(11),以与扩散板(8)分离,并且使光量调节部(11)的正交投影 发射区域覆盖任何相邻的导光板(7,17 ...)之间的边界。 这允许制造具有进一步改善的亮度均匀性的串联型照明装置。

    • An illumination device according to the present invention includes a light source; and a lightguide element including an incidence surface for receiving light emitted from the light source and an outgoing surface from which the light incident from the incidence surface goes out. The lightguide element includes a polarization selection layer for causing light of a specific polarization direction (first polarized light), among the light incident from the incidence surface, to selectively go out from the outgoing surface, and a polarization conversion layer for converting second polarized light, polarized in a different direction from that of the first polarized light, into the first polarized light. The polarization selection layer reflects the first polarized light substantially only toward the outgoing surface.
    • 根据本发明的照明装置包括:光源; 以及光导元件,其包括用于接收从光源发射的光的入射表面和从入射表面入射的光从该出射表面出来的出射表面。 光导元件包括:偏振选择层,用于使从入射表面入射的光中的特定偏振方向的光(第一偏振光)从出射表面选择性地出射;以及偏振转换层,用于将第二偏振光 ,极化与所述第一偏振光的方向不同,到第一偏振光。 偏振选择层反射第一偏振光基本上仅朝向出射面。
