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.
