An organic EL display panel includes a bulkhead for insulating an emitting
cell from an anode strip. The emitting cell is formed from an ITO strip,
a supplement electrode, an organic EL layer, an the anode strip, and at
least one supplemental bulkhead. The supplemental bulkhead prevents
sealant from being injected along a main bulkhead and into the emitting
cell, thereby preventing an inferior device from being produced and also
yield is increased.
