    Abstract: A display device includes a display panel including a display area in which an image is displayed, and a light unit that includes: a light guide plate including a light receiving surface and a light emitting surface; a light source spaced apart from the light receiving surface while facing the light receiving surface and overlapping the display area; and a light diffusion member extending between the light receiving surface and the light source. The light diffusion member includes at least one of a first pattern formed on a surface of the light diffusion member facing the light emitting surface, and a second pattern formed on another surface of the light diffusion member, thereby implementing uniform brightness across the whole surface of the display panel.

    Abstract: An optical sheet includes a base film, a prism pattern formed in a first area of the base film, and a diffusion member formed in a second area of the base film. The prism pattern has a plurality of parallel prisms on a light-exiting surface. The diffusion member includes a plurality of scatter members in the base film to scatter light, or a plurality of irregularly arranged lenses on one or more of the light-incident surface and the light-exiting surface.
