<P>PROBLEM TO BE SOLVED: To provide an inexpensive short focus type reflection screen for suppressing the reflection of external rays of light, and for efficiently reflecting video rays of light to have excellent contrast, and a method of manufacturing the reflection screen. <P>SOLUTION: Disclosed is a method of manufacturing a reflection screen including at least a lens layer having a Fresnel lens shape consisting of a plurality of unit lens having a lens surface and a non-lens surface and a support layer having an inversion shape surface having a Fresnel lens shape in this order from a video light emission side. The method is characterized by including a process of forming the support layer by using resin composition containing elastomer resin and light absorbent, a process of arranging a reflection layer at a portion of the inversion lens surface of the support layer by a heat transfer method, and a process of forming the lens layer by defining the inversion shape surface of the support layer as a molding die. <P>COPYRIGHT: (C)2013,JPO&INPIT |
