Title: LIQUID CRYSTAL PANEL WITH TOUCH SENSING FUNCTION AND LIQUID CRYSTAL DISPLAY DEVICE
Abstract:
To provide a liquid crystal panel with touch sensing function, which is capable of exhibiting satisfactorily stable antistatic function even in a humidified environment. A liquid crystal panel with touch sensing function, which comprises: a first polarizing film that is arranged on the viewing side of a liquid crystal cell with touch sensing function; a second polarizing film that is arranged on the side opposite to the viewing side; and a first adhesive layer that is arranged between the first polarizing film and the liquid crystal cell. The first adhesive layer is formed from an adhesive composition containing: a (meth)acrylic polymer (A) which contains, as monomer units, an alkyl (meth)acrylate (a1) and an amide group-containing monomer (a2); and an ionic compound (B). In addition, the first adhesive layer undergoes a small change in the surface resistivity even in a humidified environment.
