ORGANIC ELECTROLUMINESCENCE DEVICE PANEL

Abstract

There is provided an organic electroluminescence (EL) device panel including a heat dissipation member formed on a lead-out wiring electrically connected to a first electrode or a second electrode. According to the organic EL device panel of the present invention, the organic EL device is not adversely affected by heat at a time of manufacturing and driving, so deterioration of pixels of the organic EL device is not generated.
