Abstract
An adhesive film, an optical member including the same, and an optical display including the same are provided. The adhesive film is formed of a monomer mixture including a hydroxyl group-containing (meth)acrylate and an alkyl group-containing (meth)acrylate, and has a bubble generation area ratio of 0%, as measured on a specimen (length×width: 13 cm×3 cm) by repeating the described cycle 10 times, in which the specimen is prepared by sequentially stacking a polyethylene terephthalate film (thickness: 50 μm), the adhesive film (thickness: 100 μm) and a polyethylene terephthalate film (thickness: 100 μm) to have a three-layer structure, and is bent towards the PET film (thickness: 50 μm) such that the specimen is placed between frames having a gap of about 1 cm therebetween and the length of the specimen is halved and the cycle is sequentially accomplished for 24 hours.
