The display device includes a backlight unit, a color filter and a shutter panel. The color filter is formed on the backlight unit and includes a red color filter, a green color filter and a blue color filter. Each of the red color filter, green color filter, and blue color filter includes first dielectric layers including a first material having a first refractive index and second dielectric layers including a second material having a second refractive index smaller than the first refractive index, the first dielectric layers and the second dielectric layers being alternately stacked. The sum of the number of the first dielectric layers and the number of the second dielectric layers in the red color filter is different from the sum of the number of the first dielectric layers and the number of the second dielectric layers in the green color filter.
