According to one embodiment, a display device comprises a color filter layer, an illumination device and a selection layer. The illumination device illuminates the color filter layer with mixed light including first and second components. The color filter layer includes first and second filters. The selection layer includes a phase element layer including first and second phase elements, and first and second polarizers. The first phase element changes a polarization state of the mixed color light such that the first component is transmitted through the second polarizer. The second phase element changes a polarization state of the mixed color light such that the second component is transmitted through the second polarizer.
