We prepared green and red light emitting InP/ZnSeS Quantum Dots (QDs) with remarkably high quantum efficiency (up to 90%) and the narrow spectrum width (less than 40nm). These environmentally friendly QDs are very competitive for the applications of color‐saturated display compared to the previously developed Cd containing QDs. Although the III‐V compound semiconductor nanomaterials are known to be sensitive to oxidizing atmosphere, synthetic process for mass production was successfully established. To complement the vulnerability of QDs to oxygen and moisture, matrix polymer and barrier layer were designed in terms of stability and cost effectiveness. The processes including the preparation of QD resin and large area coating were also well established. To improve the properties of QD film, much effort has been put for better efficiency and stability. Also, it has been suggested that the various forms of displays utilizing the benefit of the QDs would be followed in near future.
