1. A quantum dot light emitting device comprising:

  • a light emitting device configured to generate exciting light at a first wavelength;

    a first quantum dot package layer configured to absorb the exciting light at the first wavelength, and generate converted light at a second wavelength;

    a second quantum dot package layer configured to absorb the exciting light at the first wavelength, and generate converted light at a third wavelength; and

    a dichroism component arranged between the first quantum dot package layer and the second quantum dot package, the dichroism component configured to transmit the light at the first wavelength and the light at the second wavelength, and reflect the light at the third wavelength;

    wherein the first quantum dot package layer is arranged between the light emitting device and the second quantum dot package layer, and wherein the third wavelength is shorter than the second wavelength, and longer than the first wavelength.
