    Abstract: Disclosed is a polarizing film (10) with an adhesive comprising a polarizing film (15) having a structure of amorphous cyclic polyolefin resin film (12)/polarizer (13)/protection film (14) and an adhesion layer (11) provided on an outer side of the amorphous cyclic polyolefin resin film (14), wherein the adhesion layer (11) has a gel content of 75 to 95 wt %. An optical laminate is obtained by bonding this polarizing film with adhesive (10) to one surface of a liquid crystal display glass cell (35). The second polarizing film (25) having a structure of protection film (22)/polarizer (23)/protection film (24) is bonded to the other surface of the glass cell (35) with interposing the second adhesion layer (21). When the protection film (22) is made from acetylcellulose, the second adhesion layer (21) is composed of a material having a low gel content.
