Abstract
A device for producing a color filter includes a part for storing a solution in which a light transmitting material is dissolved, a part for feeding the solution to a tip of a flying electrode, a part for applying a voltage between the tip of the flying electrode and an electro-conductive material of a color filter substrate so as to form an electrostatic field, and a part for relatively shifting the tip of the flying electrode and the color filter substrate with respect to one another in at least one of a perpendicular direction and to a horizontal direction. The solution is formed into a stringy beam which is let to fly onto the color filter substrate so that the solution is injected into a concavity formed and surrounded by a black matrix on the color filter substrate, arid forms red, green and blue light emitting layers.
