Abstract
Disclosed herein is a quantum dot composite that can maintain luminous efficiency per unit quantum dot even when a quantum dot concentration is high, and therefore can achieve a high emission intensity. The quantum dot composite includes: a matrix; and quantum dots dispersed in the matrix, wherein the matrix is composed of cellulose acetate having a compositional distribution index (CDI) of 3.0 or less, and a concentration of the quantum dots is 0.05 wt % or higher.
