Abstract

Disclosed are a solvent-free curable composition including quantum dots; and a curable monomer represented by Chemical Formula 1, a cured layer manufactured using the composition, a color filter including the cured layer, and a display device including the color filter. In Chemical Formula 1, each substituent is as defined in the specification.

Claims (23)

1. A solvent-free curable composition, comprising

quantum dots; and

a curable monomer represented by Chemical Formula 1:

wherein, in Chemical Formula 1,

R 1 and R 2 are each independently a hydrogen atom or a substituted or unsubstituted C1 to C10 alkyl group,

L 1 is a single bond,

L 2 is a substituted C1 alkylene group, and

L 3 is a substituted or unsubstituted C1 alkylene group.

2. The solvent-free curable composition of claim 1 , wherein the curable monomer represented by Chemical Formula 1 has a vapor pressure of 1.0×10 −4 torr to 5.0×10 −2 torr at 25° C.

3. The solvent-free curable composition of claim 2 , wherein the curable monomer represented by Chemical Formula 1 has a viscosity of 4 cps to 10 cps at 25° C.

4. The solvent-free curable composition of claim 1 , wherein the curable monomer represented by Chemical Formula 1 is represented by any one of Chemical Formula 3 to Chemical Formula 6:

5. The solvent-free curable composition of claim 1 , wherein the solvent-free curable composition has a viscosity of 20 cps to 40 cps at 25° C.

6. The solvent-free curable composition of claim 1 , wherein the quantum dots have a maximum fluorescence emission wavelength at 500 nm to 680 nm.

7. The solvent-free curable composition of claim 1 , wherein

the solvent-free curable composition comprises

5 wt % to 60 wt % of the quantum dots; and

40 wt % to 95 wt % of the curable monomer represented by Chemical Formula 1, based on the total amount of the solvent-free curable composition.

8. The solvent-free curable composition of claim 1 , wherein the solvent-free curable composition further comprises a polymerization initiator, a light diffusing agent, or a combination thereof.

9. The solvent-free curable composition of claim 8 , wherein the light diffusing agent comprises barium sulfate, calcium carbonate, titanium dioxide, zirconia, or a combination thereof.

10. The solvent-free curable composition of claim 1 , wherein the solvent-free curable composition further comprises a polymerization inhibitor; malonic acid; 3-amino-1,2-propanediol; a silane-based coupling agent; a leveling agent; a fluorine-based surfactant; or a combination thereof.

11. A cured layer manufactured using the solvent-free curable composition of claim 1 .

12. A color filter comprising the cured layer of claim 11 .

13. A display device comprising the color filter of claim 12 .
