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 ().
