PROBLEM TO BE SOLVED: To provide: an air bubble discharging structure enabling easy and high quality printing; a reverse printing plate using the air bubble discharging structure; a display device; a printing method; and a method of manufacturing the display device.SOLUTION: The reverse printing plate 1 includes a printing region 11a and a non-printing region 11b on the surface of a substrate 10. A recessed part 11 corresponding to a printing pattern is formed in the printing region 11a. An air bubble discharge passage 12 communicated with the recessed part 11 is provided in the non-printing region 11b, and has an opening at an end of the substrate 10. When a pattern of the reverse printing plate 1 is pressed against a flat plate-shaped blanket, air bubbles confined in the printing region 11a is released to the atmosphere through the air bubble discharge passage 12.

PROBLEM TO BE SOLVED: To provide an organic EL display device in which uniformity of a film thickness of an organic layer adjacent to a blue pixel can be improved, and a method for manufacturing the organic EL display device.SOLUTION: In the organic EL display device, a red light emitting layer 16CR and a green light emitting layer 16CG are formed by means of a coating method, and a blue light emitting layer 16CB is formed by means of a vapor deposition method as a common layer. Each of a red organic EL element 10R and a green organic EL element 10G is provided adjacent to a blue organic EL element 10B in the same pixel 10 or in an adjacent pixel 10 at least on two sides facing each other. In a side adjacent to the blue organic EL element 10B, ununiformity of a drying rate of a coating liquid in manufacturing processes is suppressed, so that deviation of the film thicknesses of the red light emitting layer 16CR and the green light emitting layer 16CG after drying can be reduced. Accordingly, uniformity or symmetry of the film thicknesses of the red light emitting layer 16CR and the green light emitting layer 16CG is improved.
Abstract:
PROBLEM TO BE SOLVED: To provide a donor substrate which is easily brought into contact with a substrate to be transferred without using a vacuum device to thereby reduce the pressure in the inner space between the donor substrate and the substrate to be transferred, and to provide a method of manufacturing a display device using the same. SOLUTION: In a base 41 of the donor substrate 40, a through-hole 45 is formed from a surface opposed to the substrate 11A to be transferred to an opposite-side surface. The donor substrate 40 and the substrate 11A to be transferred are put one over the other, and mounted on a stage 60. The pressure in a recessed part 61 is reduced by evacuation through a suction hole 62 and an inner passage 63 to thereby suck the donor substrate 40 to the stage 60. Simultaneously, the pressure in the inner space S between the donor substrate 40 and the substrate 11A to be transferred is reduced through the through-hole 45. Thus, the pressure in the inner space S is easily reduced under atmospheric pressure to easily bring the donor substrate 40 and the substrate 11A to be transferred into close contact with each other, which is very advantageous when the substrate 11A is made large-sized.

PROBLEM TO BE SOLVED: To form a line head which can bring about high image quality even if the positional accuracy of individual positional head modules and positional accuracy among the respective head modules are not increased. SOLUTION: An array of nozzles 13a of the "N"th (N is a natural number) head module 10 (N) among the head modules 10, and an array of nozzles 13a of the adjacent "N+1"th head module 10 (N+1) overlap each other in the arrangement direction (the longitudinal direction of the head module 10 in Fig.) of them. The liquid ejecting head has a droplet arrival position correcting means for correcting the arrival position of an ink droplet within the range of 0.5-1.5 times of an interval between the nozzles without an overlap by an overlap part.

PROBLEM TO BE SOLVED: To prevent an ink discharge face from being damaged and to improve a cleaning effect near ink discharge holes in an inkjet head which discharges ink for imaging from ink discharge holes onto a recording medium. SOLUTION: In the method for cleaning a printing head which has the ink discharge face 6 where an array of ink discharge holes 13 is set for discharging the ink of one color or a plurality of colors color by color, a cleaning roller 7 formed of an elastic material in a cylindrical shape is moved relatively in a state in which the cleaning roller is kept in touch with the ink discharge face 6 of the printing head, and an ink 15 inside the ink discharge holes 13 is sucked by a pressure change in the ink discharge holes 13 at a time when an outer circumferential face of the cleaning roller 7 moves in touch with the ink discharge face 6. Accordingly, the ink discharge face 6 is prevented from being damaged, and at the same time, the cleaning effect near the ink discharge holes 13 can be improved. COPYRIGHT: (C)2003,JPO

The head chips 25 are bonded to the nozzle sheet 23 while registered to the side of a grow face of the nozzle sheet to make discharge nozzles and heaters correspond to each other for each predetermined number of the discharge nozzles of the discharge nozzle array for each color. Moreover, the discharge nozzle array for each color is formed into a serpentine array so that a part of the predetermined number of discharge nozzles overlaps with respect to a paper feed direction for each predetermined number of discharge nozzles. The head chips 25 are arranged into a serpentine form to match the discharge nozzles.
