Abstract
A method for manufacturing a quantum dot layer including providing a substrate on which a first luminescence electrode, a second luminescence electrode, and a third luminescence electrode are disposed, providing a first mixed solution including a first quantum dot which has been surface-treated to have a first polarity, providing a second polarity opposite to the first polarity to the first luminescence electrode, disposing the first quantum dot on the first luminescence electrode, and drying the first mixed solution to form a first quantum dot layer.

A method for manufacturing a quantum dot layer, the method comprising:
- providing a substrate on which a first luminescence electrode, a second luminescence electrode, and a third luminescence electrode, which are spaced apart from each other on a plane, are disposed;
- providing a first mixed solution including a first quantum dot, which has been surface-treated to have a first polarity, on the first to third luminescence electrodes;
- providing a second polarity opposite to the first polarity to the first luminescence electrode;
- disposing the first quantum dot on the first luminescence electrode on which the second polarity is provided;
- and
- drying the first mixed solution to form a first quantum dot layer.
A method for manufacturing a luminescence device, the method comprising:
- providing a substrate on which a first electrode is disposed;
- providing a first mixed solution including a quantum dot which has been surface-treated with a polar material to have a first polarity on the first electrode;
- providing a second polarity opposite to the first polarity to the first electrode;
- disposing the quantum dot on the first electrode on which the second polarity is provided;
- drying the first mixed solution to form a quantum dot layer;
- and
- disposing a second electrode on the quantum dot layer.
A display device including a first pixel area, a second pixel area, and a third pixel area, the display device comprising a first luminescence device, a second luminescence device, and a third luminescence device in a one-to-one correspondence with the first pixel area, the second pixel area, and the third pixel area, respectively,
- wherein:
- each of the first to third luminescence devices includes a first electrode, a second electrode, and a quantum dot layer containing a quantum dot which is disposed between the first electrode and the second electrode, and has been surface-treated with a polar material;
- and
- the polar material is an organic compound having an amino group and a silane group, or a thiol group and a carboxyl group.
