Claim 11:
12. A method for patterning a quantum dot layer, comprising:
providing a substrate;
coating a mixture containing the ligand quantum dot of claim 6 on the substrate to form a quantum dot film, wherein the adhesion adjusting unit C has a hydrophilic-hydrophobic property opposite to that of a surface of the substrate;
exposing a preset region of the quantum dot film to ultraviolet light, so that the cleavage unit B in the cleavage-type ligand undergoes a photolysis reaction, and a molecular segment containing the adhesion adjusting unit C and obtained after decomposition is detached from a surface of the quantum dot; and
washing off an unexposed region of the quantum dot film with an organic solvent, followed by drying, to form a patterned quantum dot layer.
