Abstract: 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 ??1 to 0.045 ??1 at a peak point in a scattering intensity graph according to wave numbers measured by using small angle X-ray scattering.

Abstract: A quantum dot-polymer complex and a method for preparing the same. The quantum dot-polymer complex includes a first phase formed of a matrix resin, a globular second phase dispersed in the first phase, the second phase including a quantum dot therein, and a third phase disposed along a surface of the second phase between the first and second phases.

Abstract: A light conversion film including a first barrier film, a light conversion layer disposed on the first barrier film, the light conversion layer including a matrix resin and red quantum dots that are dispersed into the matrix resin, and a second barrier film disposed on the light conversion layer. The light conversion film satisfies following Equation (1): 5?(weight of quantum dot within light conversion layer/total weight of light conversion layer)×100×t?50, where, t is a thickness of the light conversion layer.

Abstract: A backlight unit including a plurality of light sources configured to emit primary light, and a quantum dot composite. The quantum dot composite includes quantum dot phosphors excited by primary light supplied from the plurality of light sources so as to emit secondary light having a different wavelength than the primary light, and scattering particles that are configured to scatter the primary light. The scattering particles include first scattering particles, and second scattering particles different from the first scattering particles in size and composed of particles each having a diameter in the range of 5 to 50 nm.
