Abstract: A display device includes a display panel, a backlight unit supplying light to the display panel, and a conversion sheet located between the backlight unit and the display panel. The conversion sheet includes at least one conversion pattern. A top portion of the at least one conversion pattern has a greater area than a bottom portion the at least one conversion pattern. The at least one conversion pattern includes alternately stacked at least one first conversion layer having a first refractive index and at least one second conversion layer having a second refractive index different from the first refractive index.
