Brightness homogenizing member, backlight unit, and liquid crystal display device

A brightness homogenizing member comprising:

• an incidence surface on which light from a plane light source is incident;
• and
• an emission surface that is at an opposites side of the brightness homogenizing member from the incidence surface, and that emits light, wherein:
• the brightness homogenizing member homogenizes brightness of the light from the plane light source and emits the light,
• the brightness homogenizing member has a lamination structure in which layers of high refractive index having a relatively high refractive index and layers of low refractive index having a relatively low refractive index are alternately laminated in a direction perpendicular to the emission surface,
• each of a plurality of the layers of high refractive index includes, on a surface on an emission surface side, a light bending portion that bends at least a portion of light proceeding in a direction intersecting the emission surface and causes the light to proceed in a direction in which an in-plane component parallel to the emission surface increases, and
• in a case in which where the lamination structure is planarly viewed from a lamination direction in the lamination structure, the light bending portions are provided in different positions between the plurality of the layers of high refractive index.
