Abstract: A display device includes: a blue color filter layer in a blue transmission region of an upper substrate, and including first scattering particles; a green color filter layer in a green transmission region of the upper substrate, and including second scattering particles; a red color filter layer in a red transmission region of the upper substrate; a partition wall on the upper substrate and defining a blue transmission opening, a green transmission opening, and a red transmission opening, which overlap the blue transmission region, the green transmission region, and the red transmission region, respectively; a color conversion layer including red color conversion particles and third scattering particles, and accommodated in the red transmission opening; a light emitting element layer on a lower substrate facing the upper substrate; and a filling material between the upper substrate and the lower substrate.
