Abstract
A display device includes a first substrate, and a second substrate opposing the first substrate and including a color filter layer. The color filter layer includes a red color filter, a green color filter and a blue color filter. The red color filter includes a first fluorescent dye and a first nanoparticle, and illustrates red color. The green color filter includes a second fluorescent dye and a second nanoparticle and illustrates green color. The blue color filter includes a third fluorescent dye and a third nanoparticle and illustrates blue color. Each of the first to third nanoparticles has a non-spherical shape and has maximum extinction at the first wavelength, the second wavelength and the third wavelength. The first wavelength is greater than the second wavelength, and the second wavelength is greater than the third wavelength.
