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 backlight assembly includes a light source which generates and emits light, and an optical member which is between the light source and a display panel of a display device and adjusts a path of the light emitted from the light source. The optical member includes a first base film, a second base film which faces the first base film and is closer to the display panel than the first base film, an optical pattern which is provided in plural spaced apart from each other and disposed between the first and second base films, a reflecting layer which is disposed on the optical patterns and reflects light incident to the optical member, and a wavelength conversion pattern between the first and second base films and alternately disposed with the optical patterns. The wavelength conversion pattern converts a source wavelength of the light emitted from the light source.

Abstract: A backlight unit includes a light source which generates a first light; a quantum dots member which is spaced apart from the light source by a first distance and converts the first light into a second light; a guide member which lengthwise extends in a first direction and fixes positions of the light source and the quantum dots member; and an optical member which reflects the second light. The guide member guides the first light from the light source to the quantum dots member and guides the second light from the quantum dots member to the optical member.
