Title:
POLARIZER COMPLEX AND OPTICAL LAMINATE
Document Type and Number:
WIPO Patent Application WO/2021/079614
Kind Code:
A1
Abstract:
A polarizer complex according to the present invention has a polarizer, a first reinforcement material provided to one surface side of the polarizer, and a second reinforcement material provided to the other surface side of the polarizer. The polarizer has a polarization region having a thickness of no more than 15 μm and a non-polarization region surrounded by the polarization region in plan view. The first reinforcement material has a plurality of first cells that each have an open end surface, the open end surfaces being arrayed so as to face the surface of the polarizer. The first reinforcement material has a cell region in which the first cells are present and which is present in a region corresponding to the polarization region, and a non-cell region in which the first cells are not present and which is present in a region corresponding to the non-polarization region. The second reinforcement material has a plurality of second cells that each have an open end surface, the open end surfaces being arrayed so as to face the surface of the polarizer. In the second reinforcement material, the plurality of second cells are present in a region having the second cells and corresponding to at least the non-polarization region. The non-polarization region and the non-cell region include a hardened product of an active energy ray-curable resin composition, and the hardened product included in the non-polarization region is provided in a through hole surrounded by the polarization region in plan view.
