Estimating the term…
A pressure-sensitive adhesive composition for an image display panel, a pressure-sensitive adhesive layer for an image display panel, and an optical film provided with a pressure-sensitive adhesive layer are disclosed which are free of problems regarding durability and defective appearance caused by an antistatic agent (conductive agent), and which have superior antistatic properties so as to be usable for applications such as in an image display panel. An image display panel is also disclosed in which the optical film provided with a pressure-sensitive adhesive layer is attached to the surface of the image display panel in contact with the pressure-sensitive adhesive layer without an interposed conductive layer, and a liquid crystal display device using the image display panel. Further, a liquid crystal display device is disclosed with a touch sensing function using the image display panel that can be used as various input display devices such as mobile devices.
A pressure-sensitive adhesive composition for an image display panel, comprising an ionic liquid and a (meth)acrylic polymer containing, as a monomer unit, at least one monomer selected from the group consisting of a carboxyl group-containing monomer, an amino group-containing monomer, and an amide group-containing monomer, wherein the amount of the at least one monomer is equal to or more than 1.5% by weight of the total amount of the monomers.
