<P>PROBLEM TO BE SOLVED: To provide a laminated optical film having satisfied durability even when an adhesive layer is made thin. <P>SOLUTION: The laminated optical film is constituted so that an optical film (1) having 2.0×10<SP>-11</SP>-6.0×10<SP>-11</SP>m<SP>2</SP>/N photo-elastic coefficient and a three dimensional refractive index controlled to satisfy Nz≤0.9 and Re≥80 nm and an optical film (2) exhibiting optically positive uniaxiality are laminated through the adhesive layer (A). The adhesive layer (A) contains 3-10 wt.% heterocycle-containing acrylic monomer, 0.5-5 wt.% carboxyl group-containing monomer, 0.05-2 wt.% hydroxyl group-containing monomer and 83-96.45 wt.% alkyl (metha) acrylate as monomer components and is formed from an adhesive containing a (metha) acrylic based polymer having weight average molecular weight of 1,500,000-2,800,000 and a cross-linking agent. <P>COPYRIGHT: (C)2008,JPO&INPIT |
