摘要： A light-diffusion member includes a substrate having light transparency, a plurality of light-diffusion parts formed on one surface of the substrate, and a light-absorbing layer formed in a region other than a region where the light-diffusion parts are formed, among the one surface of the substrate. Each light-diffusion part includes a light-emission end surface on the side of the substrate and a light-incident end surface of an area larger than an area of the light-emission end surface on a side opposite to the side of the substrate. The height from the light-incident end surface of the light-diffusion part to the light-emission end surface thereof is larger than the thickness of the light-absorbing layer. The plurality of light-diffusion parts are randomly arranged on the one surface of the substrate.

摘要： A light diffusing member includes a base material having a light transmitting property; a plurality of light blocking sections that are formed in a scattered manner at one surface of the base material; and a light transmissive material layer that is formed at the one surface of the base material. A thickness of the light transmissive material layer is larger than a thickness of each light blocking section. The light transmissive material layer has hollow portions in regions where the light blocking sections are formed. Each hollow portion has a shape in which a cross-section area when each hollow portion is cut at a plane that is parallel to the one surface of the base material is large on a side of the corresponding light blocking section and becomes gradually smaller with increasing distance from the corresponding light blocking section. A portion of the light transmissive material layer other than where the hollow portions are formed is a light transmitting section.

摘要： 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.
