Claim 0:
1. An organic light-emitting display device, comprising:
a lower substrate comprising a driving transistor formed on a surface thereof;
an organic light-emitting element interlocked with the driving transistor; and
an RGB color filter layer formed on the organic light-emitting element and provided with core-shell structured quantum dots that absorb light and emit the absorbed light in a form of visible light in a specific wavelength range,
wherein each of the core-shell structured quantum dots is configured such that the structure thereof is configured to be controlled by the composition thereof,
wherein the organic light emitting element is a blue organic light emitting diode,
wherein the RGB color filter layer includes: a red color filter including first core-shell structured quantum dots, of the core-shell structured quantum dots. emitting red light; and a green color filter having second core-shell structured quantum dots, of the core-shell structured quantum dots, emitting green light; and a blue color filter including third core-shell structured quantum dots, of the core-shell structured quantum dots, emitting blue light, and
wherein a core material of each of the first core-shell structured quantum dots is composed of one or more of group 13 and group 15 elements,
wherein the first second and third core-shell structured quantum dots each contain ligands on their surface,
wherein the ligands are perfluorooctanoic acid (PFOA),
wherein the first core-shell structured quantum dots have a core/shell structure of InP/ZnSe/ZnS: and
wherein the second core-shell structured quantum dots have a core/shell structure of InP/ZnSe/ZnSeS/ZnS.
