    Abstract: A color filter including a first pixel (or color conversion region) that is configured to emit a first light and a display device including the color filter. The first pixel includes a (first) quantum dot composite (or a color conversion layer including the quantum dot composite), wherein the quantum dot composite may include a matrix and a plurality of quantum dots dispersed (e.g., randomly) in the matrix, wherein the plurality of the quantum dots exhibit a multi-modal distribution (e.g., a bimodal distribution) including a first peak particle size and a second peak particle size in a size analysis, wherein the second peak particle size is greater than the first peak particle size, and a difference between the first peak particle size and the second peak particle size is less than or equal to about 5 nanometers (nm) (e.g., less than or equal to about 4.5 nm).
