Beschreibung
Zusammenfassung:	PURPOSE: A near infrared ray blocking film is provided to minimize the dependence of reflection ratio by using a bas substrate in which half-sphere patterns are formed, and to widen the bandwidth of reflection area. CONSTITUTION: A near infrared ray blocking film comprises liquid crystalline polymer films(30,40) having screw structure formed on a base plate(10), in which semi-sphere pattern(20) is formed on one side. The liquid crystalline polymer film consists of a plurality of layers. A portion of layers among the plurality of layers has a right-hand polarized light screw structure, and other layers have left-hand polarized light screw structure. The same direction polarized light screw structures are contacted each other. Each liquid crystalline polymer film consists of liquid crystalline molecules or liquid crystalline monomers, and is polymerized through UV curing.
