More Information
Summary:The invention relates to a laminate and an organic EL display device. Provided is a laminate which is capable of suppressing the occurrence of hue during black display of a display device even when exposed to a humid and hot environment. The laminate has, in this order, a light-absorbing anisotropic layer obtained from a liquid crystal composition, a bonding layer, and a polarizer. The polarizer includes a polyvinyl alcohol resin, iodine, and boron. The light-absorbing anisotropic layer contains one or more dichroic pigments and satisfies formulae (1)-(3). The liquid crystal composition includes a liquid crystal compound and a polymerization initiator. Ax, Ay, and Az represent absorbance of linearly polarized light vibrating in x, y, and z axis directions. Ax (z = 60 degrees) represents the absorbance of linearly polarized light that vibrates in the x-axis direction when the light-absorbing anisotropic layer is rotated by 60 degrees about the y-axis as the axis of rotation. Azgt, Azgt; (Ax + Ay)/2 (1); 0.001
