Abstract:
1. A manufacturing method of a display device comprising: forming a conductive film over a substrate by ejecting liquid droplets containing conductive particles by using a first liquid droplet ejecting apparatus comprising a liquid droplet ejecting head provided with a plurality of liquid droplet ejecting nozzles arranged linearly; forming a resist pattern locally on the conductive film by using a second liquid droplet ejecting apparatus comprising a liquid droplet ejecting head provided with a plurality of liquid droplet ejecting nozzles arranged linearly; forming a wiring by etching the conductive film with the resist pattern as a mask at an atmospheric pressure or a pressure close to the atmospheric pressure by using a first plasma generating device comprising a plurality of pairs of electrodes; etching the resist pattern at an atmospheric pressure or a pressure close to the atmospheric pressure by using the first plasma generating device; forming an insulating film over the wiring; and forming a contact hole by etching the insulating film at an atmospheric pressure or a pressure close to the atmospheric pressure by using a second plasma generating device provided with a pair of electrodes.
