Abstract: An object of the present invention is to provide a polarizer having a high degree of alignment and an image display device including the polarizer. A polarizer of the present invention is a polarizer formed of a polarizer-forming composition containing a liquid crystal compound, a first dichroic material, and a second dichroic material, in which the polarizer has an array structure formed of the first dichroic material and the second dichroic material.

Abstract: Disclosed is a napped artificial leather napped including: a non-woven fabric that is an entangle body of ultrafine fibers; and an elastic polymer impregnated into the non-woven fabric, the napped artificial leather having, at least on one side thereof, a napped surface formed by napping the ultrafine fibers, wherein the ultrafine fibers contain 0.5 mass % or more of a pigment (A), the elastic polymer contains 0 to 0.01 mass % of a pigment (B), and the ultrafine fibers and the elastic polymer are undyed; the napped surface has a lightness L* value of 25 or less in a color coordinate space (L*a*b* color space); and a ratio of an area occupied by the elastic polymer, observed on the napped surface, to a total area of an area occupied by the ultrafine fibers and the area occupied by the elastic polymer is 0.5% or less.

Abstract: A lighting unit has a light guiding plate having a plurality of corner portions each of which is formed by intersecting adjacent two side surfaces. The side surface between a pair of the corner portions of the light guiding plate forms a light incident face Non-light-emitting portions of a light source correspond to the pair of the corner portions of the light guiding plate, and at least one of the corner portions has an inclined face in contact with the light incident face, the side surface adjacent to the light incident face, and at least one of the top surface and bottom surface, and inclined by an angle ? (90°<?<180°) with respect to the top surface or the bottom surface.
