ORGANIC EL LIGHTING PANEL SUBSTRATE, METHOD FOR MANUFACTURING ORGANIC EL LIGHTING PANEL SUBSTRATE, ORGANIC EL LIGHTING PANEL, AND ORGANIC EL LIGHTING DEVICE

摘要

Disclosed are an organic EL lighting panel substrate and associated manufacturing method that can improve the manufacturing efficiency of an organic EL lighting panel substrate to reduce the cost and can achieve an organic EL lighting panel of excellent yield and reliability. The organic EL lighting panel substrate includes: a translucent substrate; a transparent electrode; and an auxiliary electrode. The transparent electrode is arranged on a surface of the translucent substrate and the auxiliary electrode is electrically connected to the transparent electrode. The organic EL lighting panel substrate further includes: an insulating layer at the position corresponding to an electrode lead-out part of an upper electrode of an organic EL layer that forms an organic EL lighting panel, the upper electrode being provided above the translucent substrate in such a manner as to face the transparent electrode; and a conductive layer between the translucent substrate and the insulating layer.
