A method for high resolution ink-jet print using a pre-patterned substrate employs an ink-jet printing device including an ink-jet head for discharging conductive ink droplets and a driving stage for supporting a substrate to which the conductive ink droplets are hit, to draw a fine line width pattern on the substrate. The method includes (A) forming a stripe pattern with repeated stripes on a substrate surface on which a fine line width pattern will be formed, thereby preparing a pre-patterned substrate; (B) loading the substrate to the ink-jet printing device; and (C) injecting conductive ink droplets to a substrate region where the stripe pattern is formed. An equivalent interval (d) of the stripe pattern and a fine line width (D) of the drawn fine line width pattern satisfy a relation of d

The present invention relates to a method of manufacturing a color filter, which includes forming a light-shielding portion and a pixel portion on a substrate, and reforming the pixel portion to be ink-philic by using a laser ablation. In the method of manufacturing the color filter, the laser ablation is used to prevent ink particles from being agglomerated in the pixel portion, uniformly filling with the ink, and selectively performing surface reformation of the pixel portion. The color filter manufactured by using the method has desirable pixels without color mixing.

A method for manufacturing a glass plate using laser etching includes a dipping step for dipping a glass plate, which will be etched, into an etching solution, a patterning step for irradiating laser to the glass plate dipped in the etching solution to form a pattern therein, and a washing step for washing the patterned glass plate. This method allows making a plate with a high aspect ratio and fine line widths in comparison to a conventional plate manufacturing method using photoresist for etching, and also ensures more efficient energy consumption and higher etching efficiency rather than an etching method using laser only.

A mask and an optical filter manufacturing apparatus including the same are provided. A mask used for a roll-to-roll process of forming patterns in a base film configured to move along a curved surface includes a mask body having a curved surface disposed opposite a roll around which the base film is wound and a plane surface corresponding to the reverse side of the curved surface. The curved surface of the mask body is disposed a predetermined distance apart from a curved surface of the roll. The mask and optical filter manufacturing apparatus enable formation of uniform patterns on the base film to enhance the quality of products and precisely attain the properties of the base film.
