The present invention provides reduced production cost in a method for manufacturing an organic EL device including a step of forming a light-emitting layer having a predetermined pattern ink-jet method. A drive device for aerodynamic surfaces and an aircraft including such a device. The display source 31 includes a light source, beam splitter, reflective liquid crystal display and a display source relay optical arrangement to provide an output image at an output diffuser screen. A plurality of key IDs are also received, where each one of the key IDs is associated with one of the verification keys and is encrypted as a function of the same geographic designation used to encrypt the corresponding verification key.
