PROBLEM TO BE SOLVED: To provide a novel view angle control film for windows and a method of controlling a view angle from a lateral direction of a window.SOLUTION: Disclosed are a window view angle control film comprising one or more molded resin sheets, each having protrusions on one surface, arranged together, and a method of controlling a view angle from a lateral direction of a window, which includes a step of attaching the window view angle control film on the window in such a way that convex stripes linearly extending between edges of the opposing molded resin sheets lie perpendicular to the ground. The protrusions are preferably formed such that light rays travelling at angles above a predetermined angle are totally reflected.SELECTED DRAWING: Figure 1 |
