1. A display device, comprising:
a light emitting element which emits a first light;
a layer comprising a resin, a quantum dot material, and a scatterer mixed with the resin and the quantum dot material, wherein the quantum dot material converts the first light into a second light; and
a color filter spaced apart from the layer, wherein the color filter filters a light after passed through the layer into at least one of red, green and blue lights,
wherein the scatterer is present in an amount of less than or equal to about 10 wt % based on the total weight of the layer, and
wherein the display device emits a light after passed through the color filter, and the display device displays a color region having a red apex in a region of 0.65<Cx<0.69 and 0.29<Cy<0.33 in color coordinates, a green apex in a region of 0.17<Cx<0.31 and 0.61<Cy<0.70 in the color coordinates, and a blue apex in a region of 0.12<Cx<0.18 and 0.04<Cy<0.09 in the color coordinates.
