Abstract
The present invention is to provide a polarizing plate exhibiting sufficient adhesiveness between a resin layer and a pressure sensitive adhesive layer and excellent peeling property in reworking process, and an image display device provided with the polarizing plate. The polarizing plate of the present invention includes a polarizer, and the resin layer that is in direct contact with the polarizer, in which the thickness of the polarizer is 20 μm or less, a hydrogen bonding component of a surface free energy of the resin layer is 3.5 mN/m or more, and the thickness of the polarizing plate is 70 μm or less.
Claims17
A polarizing plate comprising:
- a polarizer;
- and
- a resin layer that is in direct contact with the polarizer,
- wherein the thickness of the polarizer is 20 μm or less,
- a hydrogen bonding component of a surface free energy of the resin layer is 3.5 mN/m or more,
- the thickness of the polarizing plate is 70 μm or less, and
- wherein the resin layer is a layer obtained by polymerizing and curing a boronic acid monomer having a boronic acid group represented by the following Formula (1) and a polymerizable group, and a polyfunctional monomer having plural polymerizable ethylenically unsaturated groups:
- wherein, in Formula (1), R1 and R2 each independently represent a hydrogen atom, or a substituted or unsubstituted aliphatic hydrocarbon group, aryl group or heterocyclic group, R1 and R2 may be linked to each other to form a ring, and * indicates a bonding position.
