Zusammenfassung:	A display device includes a light-emitting module and a light-diffusing sheet stacked body. The light-emitting module includes at least one light guide plate including an upper surface and a lower surface, and light sources disposed at the lower surface side of the light guide plate. The light-diffusing sheet stacked body includes a first light-diffusing sheet disposed on the light guide plate, a second light-diffusing sheet disposed on the first light-diffusing sheet, and a third light-diffusing sheet disposed on the second light-diffusing sheet. The first light-diffusing sheet includes first protrusions at an upper surface side thereof. The second light-diffusing sheet includes second protrusions at an upper surface side thereof. The third light-diffusing sheet includes third protrusions at an upper surface side thereof. A shape of the third protrusion may be different from a shape of the first protrusions and/or a shape of the second protrusions.
