The present application may provide a flexible device comprising a pressure-sensitive adhesive layer comprising at least first and second regions having different physical properties, wherein the difference in physical properties, such as an elastic modulus or creep strain rate, which are advantageous as the difference in physical properties between the regions increases, is maintained relatively large for each region, and the difference in physical properties, such as a peel force or recovery rate, which are advantageous as the difference in physical properties between the regions decreases, is maintained relatively small for each region.

Flexible device

The present invention relates to a protective film and a polarizing plate comprising the same, and provides a protective film capable of minimizing the amount of static electricity that can be generated upon peeling the protective film.

Protective film

The present application provides a pressure-sensitive adhesive layer comprising at least first and second regions having different physical properties, wherein the difference in physical properties, such as an elastic modulus or creep strain rate is maintained relatively large for each region, and the difference in physical properties, such as a peel force or recovery rate is maintained relatively small for each region.

Pressure-sensitive adhesive layer

A specimen for analyzing the shape of an antistatic antifouling layer and a method for preparing the same are provided. The specimen includes Pt coated on an antistatic antifouling layer comprising a conductive polymer formed on a polymer substrate, so that a contrast difference between the polymer substrate layer and the antistatic antifouling layer is caused by the diffusion of Pt by means of the conductive polymer and the dyeing effect of the antifouling layer. Accordingly, it is possible to clearly distinguish the shape of the antistatic antifouling layer formed on the polymer substrate by using TEM.

Specimen for analyzing shape of antistatic antifouling layer and method for preparing same

The present application relates to a method for manufacturing a pressure-sensitive adhesive film. In an embodiment, a method for manufacturing a pressure-sensitive adhesive film having a pressure-sensitive adhesive layer and a base layer includes applying a pressure-sensitive adhesive composition on at least one side of a base layer, where the pressure-sensitive adhesive composition comprises an isocyanate compound, a metal compound and an acrylic polymer; and drying the pressure-sensitive adhesive composition at a temperature of 100&#xb0; C. or higher to form a pressure-sensitive adhesive layer on the base layer.

Method for manufacturing pressure-sensitive adhesive film

The present application relates to a pressure-sensitive adhesive composition for a foldable display and a use thereof. The pressure-sensitive adhesive composition of the present application has excellent bending reliability, and also excellent adhesive force and cohesive force.
