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.
