Abstract: A backlight unit includes a light source unit having a light source configured to emit a first light, a quantum dot sheet configured to emit a second light having a different color from the first light, a light guide plate configured to guide a light exiting from the light source unit or the quantum dot sheet, and an optical member including a prism sheet and configured to control the light exiting from the light guide plate. The quantum dot sheet includes a polymer resin and a plurality of first and second quantum dots, which are dispersed in the polymer resin. The second light is a white light obtained by mixing a red light, green light, and a blue light, and the second light has a concordance rate with an Adobe RGB color space which is no less than by about 99.9%.

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 incident surface of the light guide plate, and the prism sheet overlaps a light emitting surface of the light guide plate.

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 translation: 光学片包括通光基片，形成在基片的前主表面上的多个通光第一图案和形成在基片的后主表面上的多个通光第二图案。 第一图案从基片的前表面突出，每个第二图案的顶部与第二图案的后表面接触，而每个第二图案的较大的下表面暴露以用作光 接收面。 在光通过的第二图案之间形成具有相对较低折射率的空隙。 光学片在一个实施例中仅使用一个基片，从而降低了光学片的制造成本。
