Abstract: PROBLEM TO BE SOLVED: To prevent a bright defect and chrominance non-uniformity caused by concentration distribution inside each pixel in a color filter manufactured with an inkjet method. SOLUTION: Ink quantity discharged from an inkjet head is adjusted by controlling a landing dot diameter of the ink. Therefore, in each of the pixel an area of a region with ink concentration thinner than an average concentration value inside the pixel by >=15% is kept

Abstract: PROBLEM TO BE SOLVED: To prevent ink from continuously flowing out of a discharge orifice or a supply route when the restoring operation or replacement of an ink jet head is performed in the liquid supply route constituted within the ink jet head so as to always allow ink to flow. SOLUTION: The ink in a sub-tank 401a is supplied to the ink circulating route 121a in an ink jet head 120a through tubes 451, 455, 571, 572, 574, 553, 551 and passed through the ink circulating route 121a to be allowed to flow in a main tank 301 a through tubes 552, 554, 576, 452, 457, 458, 459. Ink continuously flows through the respective flow passages by the head difference between the tip of the tube 458 and the liquid level in the sub-tank 401a. When the restoring operation or replacement of the ink jet head 120a is performed, the continuous flow of ink is stopped by the operation of three-way valves 502, 504, 505.

Abstract: PROBLEM TO BE SOLVED: To expand a margin for broken character and color mixing by selecting the best suited ink jet head for use in terms of a nozzle hole area from among ink jet heads with different nozzle hole areas according to the shape of a pixel to be formed on an object to be colored, when manufacturing a color filter by discharging an ink from the ink jet heads. SOLUTION: Three ink jet heads 55 to be used for a color filter manufacturing device 90 are provided so that the heads 55 correspond to three primary colors R, G, B. In addition to these ink jet heads 55, the device 90 comprises a heater board for heating the different color inks and a top plate to be placed on the heater board for covering. When manufacturing the color filter, a dot pattern is illuminated by a transmitted light, then is enlarged by a microscope and this enlarged dot pattern is entered to an image processing device through a CCD camera. In the image processing device, an image is binary-coded or processed by other means to seek the diameter or area of the image. Further, it is interpreted whether a state in which dots are spread is appropriate for the actual width (or the actual area) of pixels in the color filter. Next, the hole area of a head nozzle is expanded or shrunk in accordance with the interpretation results.

Abstract: PROBLEM TO BE SOLVED: To provide the manufacturing method of the color filter which make coloring states uniform for every kinds of ink. SOLUTION: The color filter is manufactured by coloring pixels on a color filter substrate 53 by jetting ink from ink jet heads 55a, 55b, and 55c to the color filter substrate 53, which is colored by using the ink jet heads having different hole areas of ink jet nozzles for every kind of ink to be used.

Abstract: PROBLEM TO BE SOLVED: To enable image data to be recorded with high image grade and almost without density irregularities by providing a means for detecting the relative positional deviation of plural ink jet heads and a means for detecting an angle of inclination with a scan direction of the ink jet heads. SOLUTION: Each of the nozzle on each of ink jet heads is caused to discharge an ink while moving a head unit for scan relatively with a glass substrate in the X direction to insert an image of line pattern about 50mm long. In addition, a heat pulse of the same pattern is applied to all the heaters of the nozzles and a bit correction is made at an intermediate point (S12). Next, a line sensor camera measures the density of each of the serted images of line pattern while moving for scan relatively with the glass substrate in the Y direction (S13). Further, the ink discharge from each of the nozzles is determined based on the sought density of each of the line patterns (S14). Thus it is possible to obtain data on the irregularities of the ink discharge of each of the nozzles and prevent a color unevenness in a color filter from being generated and avoid the trouble of regulating the relative positions among three ink jet heads.
