Brightness homogenizing member, backlight unit, and liquid crystal display device
Abstract:
A brightness homogenizing member comprising: an incidence surface and an emission surface, the brightness homogenizing member has a lamination structure in which the brightness homogenizing member has a layer of high refractive index and a layer of 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 light emission surface side, a light bending portion that bends at least a portion of light proceeding in a direction intersecting to the emission surface and cause the light to proceed in a direction in which an in-plane component parallel to the emission surface increases, in a case 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.
