摘要： An electrostatic attraction fluid jet device of the present invention is so arranged that a nozzle (4) is formed so as to correspond to a meniscus equivalent to a tip portion in the form of a taylor cone formed in a process of an electrostatic attraction of ink (2) as a conventional fluid. A diameter of an ink-ejecting hole (4b) of the nozzle (4) is set to be substantially the same as a diameter of the tip portion, which is about to be ejected, of the meniscus (14) of ink. Moreover, the diameter of the ink-ejecting hole (4b) of the nozzle (4) is set to be equal to or less than a droplet diameter of the ink (2) which has just been ejected. Therefore, it is possible to provide an electrostatic attraction fluid jet device which can realize a recording device which has high resolution, is safe and is highly versatile.

摘要： A method is for producing an active matrix organic EL display element by an inkjet method to eject droplets (12) of a liquid via an ejection hole of a nozzle so as to form an organic EL layer. The liquid contains an organic EL layer material. An electrostatic attraction type inkjet apparatus (15) is used whose ejection hole (1b) has a diameter smaller than a diameter of the droplets (12). The droplets are ejected from the nozzle of the electrostatic attraction type inkjet apparatus (15) in such a manner that each of the droplets is 1 pl or less in amount. With this arrangement, the landed droplet dries quickly, and movement of the landed droplet is restricted. This makes it possible to form an organic EL layer accurately with low cost.
