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.

Optical sheet and backlight assembly having the same

A backlight assembly including a container having a light exiting boundary, and a light source part. The container includes a first light source supporting part supporting first and second light sources, and a reflector extending from the first light source supporting part. The reflector reflects the light from the first and second light sources to guide the light to the light exiting boundary. The first light source is disposed under the light exiting boundary and generates the light. The second light source is spaced apart from the first light source in a first direction by a first distance. The first direction is substantially parallel with the light exiting boundary. The second light source is spaced apart from the light exiting boundary in a second direction by a first depth. The second direction is substantially perpendicular to the light exiting boundary.
