Abstract

A resist composition for a black matrix, the resist composition including carbon nanotubes, a halosulfonic acid, an alcohol, an ammonium hydroxide compound, and a fluorosilane.

Claims (27)

1. A color filter display panel comprising:

a substrate comprising a pixel area;

a partition on the substrate and defining an opening, the opening corresponding to the pixel area; and

an ink layer disposed in the opening,

wherein the partition comprises a reaction product of a resist composition for a black matrix and the reaction product comprises a third compound according to Formula 3:

wherein CNT in formula (3) is carbon nanotube.

2. The color filter display panel of claim 1 , wherein

the third compound is a reaction product of carbon nanotubes, a halosulfonic acid, an alcohol, an ammonium hydroxide compound, and a fluorosilane.

3. The color filter display panel of claim 2 , wherein

the carbon nanotubes are included in the resist composition in a range of about 5 weight percent to about 8 weight percent, based on a total weight of the resist composition.

4. The color filter display panel of claim 2 , wherein

the halosulfonic acid is included in the resist composition in a range of about 1 weight percent to about 3 weight percent, based on a total weight of the resist composition.

5. The color filter display panel of claim 4 , wherein

the alcohol is included in the resist composition in a range of about 1 weight percent to about 5 weight percent, based on a total weight of the resist composition.

6. The color filter display panel of claim 5 , wherein

the ammonium hydroxide compound is included in the resist composition in a range of about 1 weight percent to about 4 weight percent, based on a total weight of the resist composition.

7. The color filter display panel of claim 6 , wherein

the fluorosilane is included in the resist composition in a range of about 9 weight percent to about 12 weight percent, based on a total weight of the resist composition.

8. A method for manufacturing a color filter display panel, method comprising:

providing a resist composition for a black matrix;

forming a partition on a substrate, the partition comprising a reaction product of the resist composition and defining an opening on the substrate; and

injecting ink into the opening,

wherein the resist composition comprises

a first compound which is a reaction product of carbon nanotubes, a halosulfonic acid, and an alcohol, and

a second compound which is a reaction product of an ammonium hydroxide compound and a fluorosilane, and

wherein the partition comprises a third compound which is a reaction product of the first compound and the second compound, wherein the third compound is formula (3)

wherein CNT in formula (3) is carbon nanotube.
