Abstract
(EN)
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.

La présente invention concerne un complexe polariseur comprenant un polariseur, un premier matériau de renforcement disposé sur un côté de la surface du polariseur et un second matériau de renforcement disposé sur l'autre côté de la surface du polariseur. Le polariseur a une région de polarisation dont l'épaisseur maximale est de 15 µm et une région de non polarisation entourée par la région de polarisation dans une vue en plan. Le premier matériau de renforcement a une pluralité de premières cellules qui ont chacune une surface à extrémité ouverte, les surfaces à extrémité ouverte étant agencées de façon à faire face à la surface du polariseur. Le premier matériau de renforcement a une région cellulaire dans laquelle les premières cellules sont présentes et qui est présente dans une région correspondant à la région de polarisation et une région non-cellulaire dans laquelle les premières cellules ne sont pas présentes et qui est présente dans une région correspondant à la région de non-polarisation. Le second matériau de renforcement a une pluralité de secondes cellules qui ont chacune une surface à extrémité ouverte, les surfaces à extrémité ouverte étant agencées de façon à faire face à la surface du polariseur. Dans le second matériau de renforcement, la pluralité de secondes cellules sont présentes dans une région comprenant les secondes cellules et correspondant au moins à la région de non-polarisation. La région de non-polarisation et la région non-cellulaire comprennent un produit durci d'une composition résineuse durcissable par rayonnement d'énergie active et le produit durci compris dans la région de non-polarisation est disposé dans un trou traversant entouré par la région de polarisation dans une vue en plan.
