OPTICAL BODY, METHOD FOR MANUFACTURING SAME, WINDOW MEMBER, SLIDING WINDOW, AND SUNLIGHT BLOCKING DEVICE

摘要

Provided is an optical body which is capable of blocking sunlight including visible light as well as suppressing glare and reflection. An optical body includes a transflective layer formed on a concave-convex surface and a second optical layer formed to enclose concave portions and convex portions on the concave-convex surface on which the transflective layer is formed. The transflective layer directionally reflects a portion of light, incident on an incidence surface at an incidence angle (&thetas;, &phgr;), in a direction other than a direction of regular reflection (−&thetas;, &phgr;+180°).
