摘要： There is provided an optical body and a display device that enable wavelength dependence of a reflectance to be reduced and reflection of incident light to be further suppressed, the optical body including: a concave-convex structure formed on a surface of a base material. An average period of concavities and convexities of the concave-convex structure is equal to or shorter than a wavelength belonging to a visible light band. A standard deviation of differences between respective positions of bottom faces of the concavities of the concave-convex structure in a normal direction of a flat surface of the base material and a median of the positions of the bottom faces is greater than or equal to 25 nm.

摘要： There is provided a new and improved optical body, a new and improved method for manufacturing an optical body, and a new and improved light emitting device that can emit light derived from a light source in more various manners. The optical body includes: a base material; and a first concave-convex structure that is formed on at least one surface of the base material and that extracts internally propagating light that is injected into an inside of the base material from a side surface of the base material. An average period of concavity and convexity of the first concave-convex structure is more than or equal to a minimum value of a visible light wavelength band and less than or equal to 10 μm.

摘要： A culture bag includes a culture portion which has a culture space configured to contain and culture a culture fluid. The culture space is an endless circumferential circulation space in which the culture fluid can circumferentially circulate. The culture fluid can continue to circumferentially circulate in one direction in the endless culture space. This suppresses complexification of flow of the culture fluid. As a result, bubbles can be suppressed from generating without decreasing culture efficiency.
