Luminescence composite, hardened member and optical sheet including the same and optical member, backlight unit and display apparatus including the optical sheet

Luminescent complex according to the present invention comprises an ionomer which covers the at least one quantum dot and quantum dots. Composites have excellent light emitting quantum efficiency, even when dispersed in a resin was a change in the width of the emission peak red, is excellent in dispersion stability, UV stability and heat / moisture stability.
