Abstract

Provided are a compound represented by specific Chemical Formula, an antireflection film including the same and a display device including the antireflection film.

Claims (37)

1 . An antireflection film comprising a compound represented by Chemical Formula 1:

wherein, in Chemical Formula 1,

R 1 , R 3 , R 4 , and R 6 are each independently a hydrogen atom or a substituted or unsubstituted C1 to C20 alkyl group,

R 2 and R 5 are each independently a hydrogen atom or a cyano group, provided that at least one of R 2 and R 5 is a cyano group,

X is a hydrogen atom, a substituted or unsubstituted C1 to C20 alkoxy group, a substituted or unsubstituted C1 to C20 alkyl group, or a substituted or unsubstituted C6 to C20 aryl group,

L is a divalent ligand, and

L is a catechol-based ligand, a 2,3-naphthalenediol-based ligand, or a 1,1′-bi-2-naphthol-based ligand.

2 . The antireflection film of claim 1 , wherein R 2 and R 5 are each a cyano group.

3 . The antireflection film of claim 1 , wherein X is:

a substituted or unsubstituted C1 to C20 alkoxy group,

a C1 to C20 alkyl group that is unsubstituted or is substituted with an unsubstituted C1 to C10 alkyl group, a C1 to C10 alkyl group that is substituted with a halogen atom, a C1 to C10 alkyl group that is substituted with a C1 to C5 alkyl group, an unsubstituted C1 to C10 alkoxy group, or a combination thereof, or

a C6 to C20 aryl group that is unsubstituted or is substituted with an unsubstituted C1 to C10 alkyl group, a C1 to C10 alkyl group that is substituted with a halogen atom, a C1 to C10 alkyl group that is substituted with a C1 to C5 alkyl group, an unsubstituted C1 to C10 alkoxy group, or a combination thereof.

4 . The antireflection film of claim 3 , wherein X is an unsubstituted C1 to C20 alkoxy group, an unsubstituted C1 to C20 alkyl group, an unsubstituted C6 to C20 aryl group, a C6 to C20 aryl group that is substituted with an unsubstituted C1 to C10 alkyl group, a C6 to C20 aryl group that is substituted with a C1 to C10 alkyl group substituted with a halogen atom, or a C6 to C20 aryl group that is substituted with an unsubstituted C1 to C10 alkoxy group.

5 . The antireflection film of claim 1 , wherein the compound is represented by one of Chemical Formula 1-1-1 to Chemical Formula 1-1-8:

6 . The antireflection film of claim 3 , wherein the compound exhibits an absorption wavelength at 400 nm to 530 nm, and has a maximum absorption wavelength at 490 nm to 520 nm of the absorption wavelengths.

7 . The antireflection film of claim 1 , wherein the compound is a dye.

8 . The antireflection film of claim 1 , wherein:

the antireflection film includes an adhesive layer and an antireflection layer on the adhesive layer, and

the compound is included in the adhesive layer.

9 . The antireflection film of claim 1 , wherein:

the antireflection film includes an adhesive layer, a dye-containing layer, and an antireflection layer on the dye-containing layer, and

the compound is included in the dye-containing layer.

10 . A display device comprising the antireflection film of claim 1 .

11 . The display device of claim 10 , wherein the display device further includes a quantum dot-containing layer.

12 . The display device of claim 11 , wherein the display device further includes a light source, a color filter, and a substrate.

13 . The display device of claim 12 , wherein:

in the display device, the quantum dot-containing layer is disposed on the light source,

the color filter is disposed on the quantum dot-containing layer, the substrate is disposed on the color filter, and the antireflection film is disposed on the substrate.

14 . The display device of claim 12 , wherein the light source is a white light source or a blue light source.

15 . The display device of claim 12 , wherein the substrate includes a glass substrate.

16 . The antireflection film of claim 1 , wherein:

Chemical Formula 1 is represented by Chemical Formula B:

in Chemical Formula B,

R 1 , R 3 , R 4 , and R 6 are each independently a hydrogen atom or a substituted or unsubstituted C1 to C20 alkyl group,

R 2 and R 5 are each independently a hydrogen atom or a cyano group, provided that at least one of R 2 and R 5 is a cyano group,

X is a hydrogen atom, a substituted or unsubstituted C1 to C20 alkoxy group, a substituted or unsubstituted C1 to C20 alkyl group, or a substituted or unsubstituted C6 to C20 aryl group, and

C1 and C2 are each independently a substituted or unsubstituted aromatic ring.
