PRINTING APPARATUS, GRAVURE PRINTING METHOD AND MANUFACTURING METHOD OF DISPLAY DEVICE USING THEREOF

摘要

A print device, a gravure print method by using the same and a manufacturing method of a display device are provided to reduce the process time by increasing the advance speed of an ink jet device or a printing substrate. A printing substrate(10) having plural openings(11) arranged adjacently with each other is prepared. Thereafter, ink is filled with the openings by means of an ink jet device having plural nozzle heads for jetting ink with different colors. The ink filled with the openings is transferred on an insulating substrate. When transferring the ink to the insulating substrate, a roller is rotated on the surface of the substrate and then the ink filled with the openings is transferred by the roller. The ink transferred to the roller is transferred to the insulating substrate. The ink jet device includes plural nozzle units having the first, second and third nozzle heads for jetting the ink with red, green and blue colors. The nozzle unit moves relatively to the printing substrate on the surface of the substrate along the extension direction of the opening and fills the ink with red, green and blue colors to the openings.
