Abstract

Provided is a wavelength conversion film-forming composition which forms a wavelength conversion film by being applied to a substrate to form a coating film and curing the coating film, the wavelength conversion film-forming composition including at least quantum dots, a volatile component, and a binder that is soluble in the volatile component and/or a binder precursor that is soluble in or compatible with the volatile component, in which the wavelength conversion film-forming composition is gellable in the presence of the volatile component.

Claims (12)

1. A wavelength conversion film-forming composition which forms a wavelength conversion film by being applied to a substrate to form a coating film and curing the coating film,

the wavelength conversion film-forming composition comprising at least quantum dots, a volatile component, and a binder precursor that is soluble in or compatible with the volatile component, and optionally further comprising a binder that is soluble in the volatile component,

wherein the wavelength conversion film-forming composition is gellable in the presence of the volatile component, and

wherein the binder precursor comprises a monofunctional (meth)acrylate.

2. The wavelength conversion film-forming composition according to claim 1 , comprising the binder having an upper critical solution temperature or the binder having a lower critical solution temperature.

3. The wavelength conversion film-forming composition according to claim 2 , comprising cellulose acylate and/or polyvinyl alcohol as the binder having the upper critical solution temperature.

4. The wavelength conversion film-forming composition according to claim 1 , further comprising a thixotropy imparting agent.

5. The wavelength conversion film-forming composition according to claim 4 , comprising the binder precursor as the volatile component, and further comprising a polymerization initiator of the binder precursor.

6. The wavelength conversion film-forming composition according to claim 1 , comprising the binder precursor and a polymerization initiator of the binder precursor,

wherein the wavelength conversion film-forming composition is caused to gel by polymerizing at least a part of the binder precursor.

7. The wavelength conversion film-forming composition according to claim 6 , further comprising the binder.

8. The wavelength conversion film-forming composition according to claim 7 , further comprising a thixotropy imparting agent.
