Title:
MANUFACTURE OF COLOR FILTER
Document Type and Number:
Japanese Patent JPH0749413
Kind Code:
A
Abstract:

PURPOSE: To provide a color filter which has a high light-shielding black matrix and also is excellent in surface flatness by coating a black matrix forming solution, after picture elements of a plurality of colors, and a repulsive layer having water repellency to the black matrix forming solution have been laminated in this order on a light transmissible base.

CONSTITUTION: Picture elements of a plurality of colors that have been patterned on a light transmissible base and a repulsive layer that has a pattern comforming to the picture elements on the picture elements are laminated in this order. Then, a black matrix forming light-shielding agent is mixed and the solution colored mainly to black is coated thereon. The repulsive layer has such a characteristic that it has a large oil repellency or water repellency to this black matrix forming solution, so that the black matrix forming solution is repelled in the repulsive layer part and does not adhere thereto, and the solution can be coated only on the picture element space part where there is no repulsive layer. Thereafter, by drying it, a color filter having a desired black matrix can be manufactured.
