    Abstract: A liquid crystal display device includes a light source, a light collection part, a liquid crystal part, and an anisotropic diffusion layer. The light source emits light. The light collection part collects the light emitted from the light source in the front direction of the liquid crystal display device so that, when an image is displayed, the light collecting property in a left-right direction is different from the light collecting property in an up-down direction. The liquid crystal part controls a transmission state of the light collected by the light collection part using a liquid crystal. The anisotropic diffusion layer anisotropically diffuses the light transmitted through the liquid crystal part.

    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: The present invention provides a light guide plate for emitting light radiated from a light source disposed at a side of the light guide plate. The light guide layer has a light incidence side for internally introducing light emitted from the light source at the side thereof; a polarization separation layer comprising a first matrix layer and a first fiber having birefringence and disposed more toward the light emission side than the light guide layer; a low refractive index layer having a lower refractive index than the refractive index of the first matrix layer; and an angle improvement layer comprising a second matrix layer having a second fiber disposed inside the second matrix layer.
