<P>PROBLEM TO BE SOLVED: To provide an adhesive type optical film for bonding glass substrates of a liquid crystal panel, which comprises a water dispersion type bonding agent as a bonding agent layer disposed on at least a surface of the optical film, and which has high adhesive strength toward a glass plate, and a liquid crystal display device equipped with the adhesive type optical film. <P>SOLUTION: The adhesive type optical film for bonding the glass substrates of the liquid crystal panel comprises the water dispersion type bonding agent as the bonding agent layer, composed of a water dispersion obtained with emulsion polymerization of a monomer mixture with at least an alkyl (meth)acrylate as a main component and a silane-based monomer, disposed on at least a surface of the optical film, wherein 0.005-1 pts.wt. silane-based monomer is included therein with respect to 100 pts.wt. monomer mixture, and is characterized in that it has the adhesive strength, measured after bonded to the glass plate to be bonded and after seven days of storing at 70°C and 20% RH, to be 1.5 times or more of the initial value. <P>COPYRIGHT: (C)2009,JPO&INPIT |
