ORGANIC EL LIGHTING PANEL SUBSTRATE, ORGANIC EL LIGHTING PANEL, AND ORGANIC EL LIGHTING DEVICE

摘要

Disclosed is an organic EL lighting panel substrate that can improve the uniformity in luminance and chromaticity in an. organic EL lighting panel plane and can suppress deterioration in reliability due to disconnection and the like caused, by art auxiliary electrode. The organic EL lighting panel substrate (10) includes: a light-transmitting substrate (11); and a transparent electrode (12). The transparent electrode (12) is arranged on one surface of the light-transmitting substrate (11). The organic EL lighting panel substrate (10) further includes an auxiliary electrode (13) electrically connected to the transparent electrode (12). The light-transmitting substrate (11) has a groove (11c), and the auxiliary electrode (13) is arranged in the groove (11c) of the light-transmitting substrate (11). The auxiliary electrode (13) is formed of a material having a volume resistivity at 20° C. in the range from 1.59×10−8 to 13×10−8 Ω·m.
