1. A color filter comprising
a first color conversion region that is configured to emit a first light,
wherein the first color conversion region comprises a quantum dot composite,
wherein the quantum dot composite comprises
a matrix and a plurality of quantum dots dispersed in the matrix,
wherein the plurality of the quantum dots exhibit a multi-modal distribution comprising 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
wherein a difference between the first peak particle size and the second peak particle size is less than about 5 nanometers,
wherein the plurality of the quantum dots comprise first quantum dots, and second quantum dots different from the first quantum dots,
wherein the first quantum dots comprise a semiconductor nanocrystal core comprising indium, phosphorus, and optionally zinc, a semiconductor nanocrystal shell disposed on the semiconductor nanocrystal core of the first quantum dots, the semiconductor nanocrystal shell of the first quantum dots comprising zinc, selenium, and sulfur, and
wherein the second quantum dots comprise a semiconductor nanocrystal core comprising indium, phosphorus, and optionally zinc, a semiconductor nanocrystal shell disposed on the semiconductor nanocrystal core of the second quantum dots, the semiconductor nanocrystal shell of the second quantum dots comprising zinc, and selenium.
