摘要： 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.

摘要： According to an exemplary embodiment, the present system and method provide a quantum dot sheet including: a color conversion film that includes quantum dots and a polymer layer in which the quantum dots are dispersed; a first barrier film that is provided one a planar surface of the color conversion film; and a phosphor pattern that has a portion located along an edge portion of the surface of the first barrier film. The phosphor pattern, which may be printed onto the quantum dot sheet, prevents deterioration of the color conversion performance of the quantum dot sheet that may occur due to oxidization.
