Provided are an adhesive film, an optical member comprising same, and an optical display device comprising same, the adhesive film comprising a (meth)acryl-based binder containing an aromatic group and a hydroxyl group, inorganic particles, and a trigger polymer, wherein the trigger polymer has a melting point of about 0° C. or more, the adhesive film has a haze of about 2% or less, and an adhesive film has a ratio of adhesive strength of about 10 or more according to Equation 1.

Adhesive film, optical member comprising same, and optical display device comprising same

Provided are: a polarizing plate; a method for manufacturing the polarizing plate; and an optical display device comprising the same, the polarizing plate having an adhesive layer, a barrier layer, a polarizer, and a protective film, which are sequentially stacked, wherein the barrier layer is formed from a barrier layer composition containing an epoxy-based compound and an antimony sulfonium-based initiator.

Polarizing plate, method for manufacturing polarizing plate, and optical display device comprising same

An adhesive film for polarizing plates, a polarizing plate including the same, and an optical display including the same are provided. An adhesive film for polarizing plates is formed of an adhesive composition including a (meth)acrylic copolymer and a cellulose ester binder. The (meth)acrylic copolymer contains an alkyl group, a hydroxyl group, an alicyclic group, and a hetero-alicyclic group. The adhesive film has a modulus at 30&#xb0; C. of about 100,000 Pa or more.

Adhesive film for polarizing plate, polarizing plate and optical display comprising the same

An adhesive composition for polarizing plates includes a (meth)acrylic copolymer prepared by copolymerization of a monomer mixture and a curing agent. The monomer mixture includes a hydroxyl group-containing (meth)acrylic monomer, a tertiary amine group-containing (meth)acrylic monomer and a monomer having a glass transition temperature (Tg) of about 100&#xb0; C. or greater. The adhesive composition has a gel fraction of about 50% or greater after aging for 12 hours. An adhesive film is formed from the adhesive composition. An optical display includes the adhesive film.

Adhesive composition for polarizing plate, polarizing plate including the same, and optical display including the same

An adhesive film of the present invention comprises a (meth)acrylate-based copolymer and a cross-linking agent, and a gel fraction thereof is approximately 50-95%, and a ratio of change G' in storage modulus thereof, represented by the following formula 1, is 20% or less.&#x2032;=(7&#x2212;1)/1&#xd7;100&#x2003;&#x2003;[Formula 1] (In formula 1, G1 is a storage modulus at 25&#xb0; C. when the adhesive film is matured at 23&#xb0; C. and a relative humidity (RH) of 55% for one day, and G7 represents a storage modulus at 25&#xb0; C. when the adhesive film is matured at 23&#xb0; C. and an RH of 55% for seven days.)

Adhesive film and display member using same

A polarizing plate including an adhesive film for polarizing plates and an optical display including the polarizing plate, the adhesive film being formed from an adhesive composition for polarizing plates, the adhesive composition including a tertiary amine group-containing (meth)acrylic copolymer; a cellulose resin; an isocyanate compound; and a metal chelate compound.
