Abstract: A color filter includes a substrate including pixel areas and a light-shielding area which is disposed between adjacent pixels areas; and a color conversion layer which color-converts incident light of an incident color and emits color-converted light toward the substrate, the color conversion layer including a first color conversion pattern in a first pixel area among the pixel areas and with which the incident light of the incident color is converted into light of a first color; and a second color conversion pattern in a second pixel area among the pixel areas and with which the incident light of the incident color is converted into light of a second color; and a partition wall in the light-shielding area and between the first color conversion pattern and the second color conversion pattern, the partition wall including a light-scattering material which scatters light incident thereto.
