Abstract

A color filter composition comprises a mixture of a binder and a monomer in a predetermined ratio, a pigment, and a solvent. The predetermined ratio is a ratio of the binder to the monomer and ranges from about 50:50 to about 60:40. The color filter composition further comprises a solid powder having a weight percent in the color filter composition ranging from about 12% to about 18%, wherein the solid powder includes the pigment. The pigment has a weight percent in the solid powder ranging from about 28% to about 38%.

Claims (32)

1. A color filter composition for a display device, comprising:

a mixture of a binder and a monomer at a predetermined ratio;

a pigment;

a solid powder having a weight percent in the color filter composition ranging from about 12% to about 18%; and

a solvent,

wherein the color filter composition is capable of being coated over a substrate to form a color filter thin film capable of being patterned using a photo process or a photolithography process.

2. The color filter composition as recited in claim 1 , wherein the solid powder includes the pigment.

3. The color filter composition as recited in claim 2 , wherein the pigment has a weight percent in the solid powder ranging from about 28% to about 38%.

4. The color filter composition as recited in claim 1 , wherein the predetermined ratio is a ratio of the binder to the monomer and ranges from about 50:50 to about 60:40.

5. The color filter composition as recited in claim 1 , wherein the pigment is at least one of a red pigment, a green pigment and a blue pigment.

6. The color filter composition as recited in claim 1 , wherein the pigment includes a mixture of a plurality of pigments, each pigment of the plurality of pigments having a different color index.

7. The color filter composition as recited in claim 1 , wherein a viscosity of the color filter composition ranges from about 3.3 mPa·s to about 4.1 mPa·s at about 25° C.

8. The color filter composition as recited in claim 1 , further comprising a black material for forming a black matrix.

9. The color filter composition as recited in claim 1 , wherein the color filter composition is coated on a substrate using a slit coating process.

10. A color filter composition for a display device, comprising:

a solvent;

a pigment;

a solid powder having a weight percent in the color filter composition ranging from about 12% to about 18%; and

wherein the color filter composition is capable of being coated over a substrate to form a color filter thin film capable of being patterned using a photo process or a photolithography process.

11. The color filter composition as recited in claim 10 , wherein the pigment has a weight percent in the solid powder ranging from about 28% to about 38%.

12. The color filter composition as recited in claim 11 , wherein the pigment is at least one of a red pigment, a green pigment and a blue pigment.

13. The color filter composition as recited in claim 10 , further comprising:

a binder; and

a monomer, wherein a ratio of the binder to the monomer ranges from about 50:50 to about 60:40.

14. A color filter composition for a display device, comprising:

a binder;

a monomer;

a dispersant;

a pigment;

a solid powder having a weight percent in the color filter composition ranging from about 12% to about 18%; and

at least one of a filing, a surfactant, an adhesion accelerant, an antioxidant, an ultraviolet absorbent, and adhesion initiator,

wherein the color filter composition is capable of being coated over a substrate to form a color filter thin film capable of being patterned using a photo process or a photolithography process.
