    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 updown 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.
