BRIGHTNESS ENHANCEMENT FILM, POLARIZING PLATE AND IMAGE DISPLAY DEVICE

摘要

An aspect of the present invention relates to a brightness enhancement film, wherein a high refractive index layer and a low refractive index layer with an average refractive index that is lower than that of the high refractive index layer are directly laminated, and which includes a concavo-convex shape including concave portions and convex portions in an interface shape of an interface between the high refractive index layer and the low refractive layer, with the high refractive index layer including a lyotropic liquid-crystalline compound, and an outermost surface on the low refractive index layer side being a flat surface.
