Abstract: A display device includes: a display unit; and a color converter on the display unit and including a color converting layer and a transmission layer, a bank between the color converting layer and the transmission layer, a first layer on the color converting layer, the transmission layer, and the bank, a second layer on the first layer, a third layer on the second layer, and a color filter on the third layer. The first layer includes a first sub-layer with a first refractive index equal to or greater than about 1.4 and less than about 1.8, and a second sub-layer with a second refractive index equal to or greater than about 1.8 and equal to or less than about 2.0. The second layer has a refractive index smaller than those of the first layer. The third layer has a refractive index greater than that of the second layer.
