    Abstract: A light conversion member includes a base substrate, a first light conversion layer disposed on the base substrate and including a plurality of first quantum dots that converts first light into light with a first color, a second light conversion layer disposed between the base substrate and the first light conversion layer and including a plurality of second quantum dots that converts the first light into light with a second color. Each of the first quantum dots includes a first core that converts the first light into light with the first color; a first shell surrounding the first core and including an organic material; and a second shell surrounding the first shell and including an inorganic material.
