Embodiment

[0105] The nozzle width is 25400μm, the nozzle resolution is 1440dpi, the nozzle pitch P is 25400 / 1440=17.6μm, the pixel size is a=300μm, b=100μm, the coating area size is c=220μm, d=20μm, relative to the nozzle The number is N=c / P=220 / 17.6 12. The coating test was carried out under the conditions that the number M of droplets in the relative moving direction was 1, the coating amount in a pixel (filling amount in a pixel) V was 300p1, and the average Q of one droplet was 40p1.

[0106] Under this condition, the number n of remaining nozzles that satisfies the application amount in a pixel can be obtained by substituting a specific numerical value into Equation 1, and the number n of remaining nozzles is 4 or less.

[0107] As a result, the number i of combinations of ink jet nozzles 52 was 495.

[0108] Therefore, by using the ink nozzles 52 of 495 or less combinations (for example, 50 combinations) (for example, 50 combinations) (selection of the discharge state) to apply ...

Abstract

The present provides a method and apparatus for manufacturing color filter, the inventino is to apply a color material discharged from an ink jet nozzle on the center portion of a pixel region, irrespective of the screen sizes and size increase of a glass substrate. [MEANS FOR SOLVING PROBLEMS] A direction parallel to the longitudinal direction of an ink jet head bar (5) is set in the longitudinal direction of a pixel, and a relative moving direction of the inkjet head bar (5) is set in a direction orthogonally intersecting with the longitudinal direction of the pixel.

Description

technical field [0001] The present invention relates to a method of manufacturing a color filter on a glass substrate using an inkjet nozzle and an apparatus thereof. Background technique [0002] Conventionally, a method of producing a color filter on a glass substrate using an inkjet nozzle has been proposed (see Patent Document 1). [0003] Specifically, at least a transparent dye-absorbing layer is provided on the transparent substrate, and the area between pixels to be different colors is used as a non-staining area with anti-staining properties, and at the site where pixels to be the same color are adjacent to each other, A color filter is produced by applying a coloring agent to and dyeing the plurality of pixel portions to be the same color including the inter-pixel region without interruption. [0004] In addition, the method of main scanning and drawing the entire screen in parallel in a straight line is adopted. By arranging the pixel arrangement designed so that...
