Abstract:
The present invention is a active-driving organic EL light emission device comprising an organic EL element comprising an organic luminous medium between an upper electrode and a lower electrode, and a thin film transistor for driving this organic EL element, wherein light emitted from the organic EL element is taken out from the side of the upper electrode, and the upper electrode comprises a main electrode formed of transparent conductive material, and an auxiliary electrode formed of a low-resistance material. According to the active-driving organic EL light emission device of this structure, the numerical aperture can be made large. Additionally, the sheet resistivity of the upper electrode can be made low even if luminescence is taken out from the side of the upper electrode. Thus, it is possible to provide an active-driving organic EL light emission device making it possible to display images having a high brightness and a homogenous brightness; and a method for manufacturing the same.
