Classification: CPC G  B | IPC G

Claim 5:
6. A color filter comprising:
a substrate including a top surface having an ink-philic property;
a bank formed on the substrate to partition a plurality of pixel units into each other, and
including a side surface having an ink-philic property and a top surface having an ink-repellent property;
a plurality of structures formed in the pixel unit, having a width narrower than a width of a pixel unit of the plurality of pixel units and a height lower than a height of the bank, including an insulating material that is transparent and etchable, and including a surface having the ink-philic property; and
an ink film having a height higher than a height of a structure of the structures and filled in the pixel unit,
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, and
wherein the structure has a wall structure.
