Abstract
A method is for producing an active matrix organic EL display element by an inkjet method to eject droplets () 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 () is used whose ejection hole () has a diameter smaller than a diameter of the droplets (). The droplets are ejected from the nozzle of the electrostatic attraction type inkjet apparatus () 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.
