Abstract
An electrode of the organic EL device includes a substantially rectangular electrode region that contacts an organic layer, a terminal section to which an external drive circuit is connected, and a conductive section that electrically connects the terminal section to the electrode region. The conductive section includes a first joint connected to the terminal section, a second joint connected to the outer periphery of the electrode region, and a conductive section main body that extends between the first joint and the second joint to electrically connect the first joint to the second joint. Therefore, the difference of magnitude between currents flowing at respective positions in a luminous region in the organic EL device is lessened.
