    • A light diffusion member includes a light-transmissive base, a plurality of light diffusion portions, a connecting portion, and a light absorbing layer. The light diffusion portions are arranged on one surface of the base and have light-incident end surfaces each positioned on the side away from the base and having a larger area than a light-emergent end surface thereof. The connecting portion connects at least two adjacent ones of the plural light diffusion portions to each other, and is positioned near the light-incident end surfaces of the adjacent light diffusion portions. The light absorbing layer is formed on the one surface of the base in a region different from a region where the light diffusion portions are formed. A size from the light-incident end surface to the light-emergent end surface of the light diffusion portion is larger than a thickness of the light absorbing layer.

    • A display device (1) includes a light diffusing sheet (10) and a display section (5). The display section (5) includes a backlight section, and a liquid crystal panel that serves as a liquid crystal display element section. The backlight section includes a light source such as a light emitting diode or a cold-cathode tube, and a light guide plate for guiding, to the liquid crystal display element section, light which is emitted from the light source and is subjected to internal reflection. The light diffusing sheet (10) is configured by forming, on a substrate (6), a plurality of light diffusing sections (7) each having an inverse tapered shape. In the display device (1), the light diffusing sheet (10) is provided on a front surface of the display section (5) such that the substrate (6) is located on a light exit surface side of the light diffusing sheet (10). It follows that the substrate (6) covers a forefront surface of the display device (1). It is therefore possible to, for example, prevent the display device (1) from being contaminated or prevent the plurality of light diffusing sections (7) from being damaged.
    • 显示装置(1)包括光漫射片(10)和显示部(5)。 显示部分(5)包括背光部分和用作液晶显示元件部分的液晶面板。 背光部分包括诸如发光二极管或冷阴极管的光源和用于将从光源发射并经受内部反射的光引导到液晶显示元件部分的导光板 。 光漫射片(10)通过在基板(6)上形成多个具有倒锥形的光散射部(7)而构成。 在显示装置(1)中,在显示部(5)的前表面设置有光扩散片(10),使得基板(6)位于光漫射片(10)的光出射面侧 )。 因此,衬底(6)覆盖显示装置(1)的最前面。 因此,例如可以防止显示装置(1)被污染或防止多个光散射部(7)被损坏。
