A light conversion composite including a matrix resin and quantum dot-polymer beads dispersed within the matrix resin. The light conversion composite has a wave number q of 0.0056 Å -1 to 0.045 Å -1 at a peak point in a scattering intensity graph according to wave numbers measured by using small angle X-ray scattering.
