Abstract: A color filter panel includes: a base substrate having a first pixel area, a second pixel area, and a light blocking area between the first pixel area and the second pixel area; a first color filter on the base substrate in the first pixel area; a second color filter on the base substrate in the second pixel area; a first photoluminescence pattern on the first color filter in the first pixel area and configured to convert a color of light; and a second photoluminescence pattern on the second color filter in the second pixel area and configured to convert a color of light. The second photoluminescence pattern partially overlaps the first photoluminescence pattern in the light blocking area.
