Abstract

A color filter forming method, includes: forming a bank on a substrate; making the substrate and part or all of the bank lyophilic; and coating a liquid repellent on part or all of an upper surface of the bank.

Claims

1. A color filter forming method, comprising:

forming a bank on a substrate;

making the substrate and part or all of the bank lyophilic; and

coating a liquid repellent on part or all of an upper surface of the bank.

2. The color filter forming method, wherein the liquid repellent according to claim 1 is deposited on a plate member which is a different member from the substrate, and the liquid repellent transfers to a part or all of the upper surface of the bank as the plate member and the upper surface of the bank on the substrate come into contact with each other.

3. The color filter forming method, wherein a material of the bank according to claim 1 is an inorganic material or an organic material.

4. The color filter forming method, wherein a height of the bank according to claim 1 is more than 1 μ

m.

5. The color filter forming method, wherein the bank according to claim 1 is disposed on a shielding layer.

6. The color filter forming method, wherein making the substrate and a part or all of the bank lyophilic according to claim 1 includes at least one processing of ozone oxidation processing, plasma processing, corona processing, UV irradiation processing, electron beam irradiation processing, acid treatment, and alkali treatment.

7. The color filter forming method, wherein the plate member according to claim 2 is flat plate-shaped or roll-shaped.

8. The color filter forming method, wherein a material of the plate member according to claim 2 is an elastomer including at least a siloxane structure.

9. The color filter forming method, wherein the liquid repellent according to claim 1 is a high molecule which is a silane coupling agent or a high molecule exhibiting liquid repellency.
