Document Type and Number:
WIPO Patent Application WO/2021/079622
Kind Code:
A1
Abstract:
This polarizer composite includes a polarizer, a retardation layer, and a reinforcing material. The polarizer includes a polarization area with a thickness of 15 μm or less and a non-polarization area surrounded by the polarization area in a planar view. The retardation layer includes: a retardation area that has retardation characteristics and that is present in an area corresponding to the polarization area; and a non-retardation area that does not have retardation characteristics and that is present in an area corresponding to the non-polarization area. The reinforcing material includes a plurality of cells having an open end face. The open end faces are arranged so as to face the surface of the polarizer. The reinforcing material includes a cell area that is present in an area corresponding to the polarization area and in which the cells are present, and a non-cell area that is present in an area corresponding to the non-polarization area and in which the cells are not present. The non-polarization area, the non-retardation area, and the non-cell area include a cured product of an active energy ray-curable resin.
