Claim Text:
1. A method for fabricating an organic electroluminescence device comprising: preparing an organic electroluminescence device having a lower electrode, an organic layer including an emitting layer, an upper electrode, and a shorted part in which the lower electrode and the upper electrode are shorted; and irradiating a part surrounding the shorted part with an ultrashort pulse laser, the ultrashort pulse irradiation altering a material composing the lower electrode or the upper electrode such that an altered part is formed, and forming a hollow space, which is different from the altered part, between the lower electrode and the upper electrode in a region surrounded by the altered part in a plan view, wherein, when irradiating the part surrounding the shorted part with the ultrashort pulse laser, the shorted part is not irradiated, and a pulse width of the ultrashort pulse laser is 100 fs to 20 ps.
