<P>PROBLEM TO BE SOLVED: To provide an optical film capable of reducing dispersion, and capable of preventing a contrast from getting low, even when mounted on an image display formed highly precisely with 50 μm or less of pixel pitch. <P>SOLUTION: The optical film 12 with a pressure-sensitive adhesive is laminated with the optical film such as a polarizing film 11 and the pressure-sensitive adhesive 6, the pressure-sensitive adhesive 6 contains a pressure-sensitive adhesive resin containing an acrylic polymer as a main component, and fine particles comprising an acrylic resin having 0.1-4 μm of average particle size, and having a refractive index difference to a polymer constituting the pressure-sensitive adhesive resin within a range of 0.01-0.05, and the fine particles exist at a ratio of 10-40 pts.wt. per 100 pts.wt. of the pressure-sensitive adhesive resin, in the optical film with the pressure-sensitive adhesive. Other optical layer is laminated onto the optical film with the pressure-sensitive adhesive, to form a laminated optical member, and the optical film with the pressure-sensitive adhesive is combined with image display elements such as liquid crystal cells, to constitute the image display. <P>COPYRIGHT: (C)2010,JPO&INPIT |
