摘要

Disclosed are an optical film for a display and a light source assembly and a liquid crystal display including the same. The optical sheet includes: a first substrate; a first optical modulation layer which is formed on the upper side of the first substrate; a prism part; and an upper optical pattern part. The prism part is extended in a first direction and includes a prism lower end, a prism inclined plane inclined against the substrate, and a prism upper end which is parallel to the substrate and narrower than the prism upper end.
