Claims
- 1. A device for producing a color filter having:
means for storing a solution in which a light transmitting material is dissolved; means for feeding the solution to a tip of a flying electrode; means 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 means for relatively shifting the tip of the flying electrode and the color filter substrate to a perpendicular direction and to a horizontal direction; wherein 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, and forms red, green and blue light emitting layers.
- 2. The device for producing a color filter according to claim 1, wherein a thickness of the stringy beam of the solution is varied by controlling the electrostatic field.
- 3. The device for producing a color filter according to claim 1, wherein the amount of injection of the solution is varied by controlling a velocity of relative shifting of the tip of the flying electrode and the color filter substrate to a perpendicular direction.
- 4. The device for producing a color filter according to claim 1, wherein the means for forming an electrostatic field includes applying a voltage obtained by in-series overlapping of a pulse voltage on a direct current voltage of bias, and the stringy beam is intermittently cut by controlling the electrostatic field.
- 5. The device for producing a color filter according to claim 1, wherein the solution is injected into the concavity formed and surrounded by the back matrix and, after vaporizing off of a solvent, the injection of the solution is repeated.
- 6. The device for producing a color filter according to claim 1, wherein the device has a plurality of the flying electrodes.
