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.
Claims28
