A quantum dot ink, a method of manufacturing a display panel, and the display panel are provided. The quantum dot ink includes an organic solvent and quantum dots dispersed in the organic solvent. The quantum dots include luminescent quantum dots and blocking quantum dots. Dispersion effect of the quantum dot ink during inkjet printing is inhibited by adding the blocking quantum dots into the quantum do ink. This can prevent a coffee ring effect, and enhance smoothness and uniformity of a quantum dot film surface, thereby allowing the display panel to exhibit excellent display quality.
