Abstract: A backlight unit includes a light conversion member; a light guide plate including a light exit surface, a rear surface facing the light exiting surface, and connection surfaces including a first surface and a second surface facing each other to connect the light exit surface and the rear surface; a reflective member; and a light source emitting a first color light incident to the first surface and a portion of the first color light reaches the second surface on which the reflective member is disposed to specularly reflect the portion of the first color light. The light conversion member is disposed on the light exit surface, receives the first color light from the light guide plate, and emits a second color light different from the first color light.

Abstract: Provided are a display device and a method of fabricating the display device. The display device includes a display panel, a backlight unit, and a light emitting sheet. The backlight unit is disposed under the display panel to provide light to the display panel. The light emitting sheet is disposed between the display panel and the backlight unit. The light emitting sheet includes a lower film, a first light emitting resin pattern layer, an upper film, and a second light emitting resin pattern layer. The first light emitting resin pattern layer is disposed on the lower film and includes a plurality of first protrusions and a plurality of first grooves defined between the first protrusions. The upper film is disposed on the first light emitting resin pattern layer. The second light emitting resin pattern layer is disposed between the first light emitting resin pattern layer and the upper film.

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%.
