<p><P>PROBLEM TO BE SOLVED: To provide a transmission type screen with an improved design and manufacturing method thereof capable of increasing the adhesion between a light control sheet and a light diffusion layer, particularly the adhesion under a high temperature condition, while preventing yellowing of an adhesive layer. <P>SOLUTION: The transmission type screen includes: plural unit light transmission parts 47 constituting a part of an image light emitting surface 45a; a light control sheet 45 having plural unit light absorbing parts 48 disposed alternately with the plural unit light transmission parts 47; a light diffusion layer 55 disposed at the image light emitting side; and a lamination having a curved surface including an adhesive layer 50 adhering therebetween. The adhesive layer 50 is a hardened photocuring adhesive composition 51 including two functional urethane (meth) acrylate of (A) average molecular weight of 15,000 or more and 25,000 or less and (B) average molecular weight of 5,000 or more and 8,000 or less, (C) mono functional (meth) acrylate monomer, (D)radical polymerization initiator and (E) antioxidant. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
