1. a display base plate, comprise underlay substrate and be formed at the multiple pixel cells on described underlay substrate, described each pixel cell comprises multiple sub-pixel unit;

  • It is characterized in that, comprise the quantum dot light emitting device away from underlay substrate side in described each sub-pixel unit;

    Described quantum dot light emitting device comprises quantum dot light emitting layer, and described quantum dot light emitting layer corresponding to multiple described sub-pixel unit is wholely set with layer;

    Described sub-pixel unit comprises the first kind sub-pixel unit that coloured light wavelength is greater than the coloured light wavelength of quantum dot light emitting layer;

    Described first kind sub-pixel unit comprises the light conversion structure of the close underlay substrate side corresponding with quantum dot light emitting device, and described light conversion structure is used for the coloured light that quantum dot light emitting device sends to be converted into coloured light corresponding to each described first kind sub-pixel unit.
