Abstract:
A light-diffusing-member manufacturing method includes a step of forming a light diffusion portion on one surface side of a base, by developing an exposed negative photosensitive resin layer with an alkali developing solution, and a step of performing an acid treatment on the light diffusion portion with an acid solution, after removing the alkali developing solution which is adhered to the light diffusion portion and suspended matter in the alkali developing solution in the negative photosensitive resin layer, so as to lower an ionization degree of the negative photosensitive resin layer which is in an ionized state due to the alkali developing solution.

A liquid crystal display (1) includes a liquid crystal panel (4), a backlight (2), and a light-diffusing member (7). There exist azimuths in which a transmittance of the liquid crystal panel (4) and a luminance of the backlight (2) are higher than a transmittance and a luminance in a direction of a normal. The azimuth in which the transmittance of the liquid crystal panel (4) is higher coincides with the azimuth in which the luminance of the backlight (2) is higher.

Abstract:
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.
