Claim 0:
1. A color filter comprising:
a substrate;
a bank formed on the substrate to partition a plurality of pixel units into each other;
a plurality of structures formed on a pixel unit of the plurality of pixel units, and having a width narrower than a width of the pixel unit, and a height lower than a height of the bank; and
an ink film filled in the pixel unit and having a height higher than the height of a structure of the structures,
wherein, between a pair of opposing walls of the bank, each of the structures longitudinally extends on a surface of the substrate in a same direction as a remaining of the structures,
wherein an other pair of opposing walls extends between the pair of opposing walls to confine the ink film within the bank,
wherein the pair of opposing walls and the other pair of opposing walls completely encircle the structures to prevent flow of the ink film out of the bank,
wherein said each of the structures longitudinally extends in a width direction of the bank,
wherein, in the bank, an entirety of the surface of the substrate is covered by the structures and the ink film,
wherein the structure has a wall structure,
wherein a surface of the plurality of structures has an ink-philic property,
wherein a surface, which makes contact with the ink film, of the bank has an ink-philic property,
wherein the plurality of structures includes a transparent material, and
wherein a top surface of the bank has an ink-repellent property.
