Abstract: An optical member, a polarization member, and a display device are provided. The optical member includes a substrate, and a functional layer provided on the substrate, the functional layer including a high refractive layer and a low refractive layer, wherein the high refractive layer has a higher refractive index than that of the substrate and a diffraction grating structure, and the low refractive layer has a lower refractive index than that of the high refractive layer, wherein an interface between the substrate and the high refractive layer and an interface between the high refractive layer and the low refractive layer are in states in which components of the respective layers with the respective interfaces therebetween are compatible with each other.

Abstract: A light deflection diffusion sheet, a stacked light deflection diffusion sheet, and a stacked optical sheet that are used in a liquid crystal panel are disclosed. A liquid crystal display (LCD) device include a liquid crystal panel having a length direction and a width direction; a surface light emitting module; a base sheet disposed between the liquid crystal panel and the surface light emitting module; a light diffusion layer disposed on a surface of the base sheet facing the surface light emitting module and diffusing light incident from the surface light emitting module; and a light deflection layer disposed on a surface of the base sheet facing the liquid crystal panel and controlling a travel direction of the light.
