Organic el lighting panel substrate, method for manufacturing organic el lighting panel substrate, organic el lighting panel, and organic el lighting device

摘要

Provided is an organic EL illumination panel substrate, and a manufacturing method therefor, that improves the manufacturing efficiency and reduces the cost for an organic EL illumination panel substrate and that is capable of achieving an organic EL illumination panel with superior yields and reliability. The organic EL illumination panel substrate has a light transmitting substrate (11), a transparent electrode (12) and an auxiliary electrode (13). The transparent electrode (12) is arranged on one face of the light transmitting substrate (11). The auxiliary electrode (13) is electrically connected to the transparent electrode (12). On the light transmitting substrate (11), there is an insulating layer (14) at a position corresponding to an electrode lead-out section for an upper electrode of an organic EL layer that is disposed facing the transparent electrode (12) and that constitutes the organic EL illumination panel. There is a conductive layer between the light transmitting substrate (11) and the insulating layer (14).
