Zusammenfassung:	PURPOSE: An optical sheet, a backlight unit including the same, and a liquid crystal display device are provided to improve display quality by uniformly diffusing the light on the whole surface of the display region of the liquid crystal panel. CONSTITUTION: A base(110) includes a first surface(111a) and a second surface(111b) to face each other. A prime unit(120) is positioned on the base. The H1 is a vertical distance from one point of the first surface to the second surface. The H2 is a vertical distance from the other point of the first surface to the second surface. At least one side of the first surface and the second surface of the base has a wave shape. The prism unit includes a plurality of beads and a base part(125).
