Abstract: An optical sheet includes a light-passing base sheet, a plurality of light-passing first patterns formed on a front major surface of the base sheet, and a plurality of light-passing second patterns formed on a rear major surface of the base sheet. The first patterns protrude from the front surface of the base sheet, a top portion of each of the second patterns makes contact with the rear surface of the second patterns while a larger lower surface of each of the second patterns is exposed to serve as a light receiving surface. Voids having relatively low refractive indices are formed between the light-passing second patterns. The optical sheet employs just one base sheet in one embodiment, thereby reducing a manufacturing cost of the optical sheet.

Abstract: A light guiding plate includes: a light guiding substrate; and a plurality of optical scattering patterns positioned on a first surface of the light guiding substrate. The plurality of optical scattering patterns respectively includes a binder, a scattering particle and a semiconductor nanocrystal. A color of light emitted from the plurality of optical scattering patterns is substantially the same.

Abstract: A prism sheet includes: a first portion including a prism elongated in a first direction; and a second portion including a prism elongated in a second direction different from the first direction. The second direction is vertical to a light incident surface of a light guide plate of a backlight unit, a light source of the backlight unit faces the light indicent surface of the light guide plate, and the prism sheet overlaps a light emitting surface of the light guide plate.
