Abstract
A method of forming a red light-emitting layer includes: a light-emitting layer formation step of forming a red light-emitting layer containing either quantum dots each including a core or quantum dots each including a core and a shell; and a light-emitting layer processing step of treating the quantum dots in the red light-emitting layer with a treating agent after the light-emitting layer formation step of forming the red light-emitting layer.
Claims21
A method of forming a light-emitting layer, the method comprising:
- a light-emitting layer formation step of forming a light-emitting layer containing either quantum dots each including a core or quantum dots each including a core and a shell;
- and
- a light-emitting layer processing step of treating the quantum dots in the light-emitting layer with a reducing agent after the light-emitting layer formation step.
A display device comprising:
- a first subpixel, a second subpixel, and a third subpixel;
- a first light-emitting layer provided in the first subpixel and containing either first quantum dots each including a core or first quantum dots each including a core and a shell;
- a second light-emitting layer provided in the second subpixel and containing either second quantum dots each including a core or second quantum dots each including a core and a shell;
- and
- a third light-emitting layer provided in the third subpixel and containing either third quantum dots each including a core or third quantum dots each including a core and a shell, wherein
- the first light-emitting layer contains an element that has a lower electronegativity than all elements contained in the first quantum dots,
- the second light-emitting layer contains an element that has a lower electronegativity than all elements contained in the second quantum dots, and
- the third light-emitting layer contains an element that has a lower electronegativity than all elements contained in the third quantum dots.
